same error for MolecularAnalysis, CircadianInfluence, NeuralComputation, FleshShaping, SkinHardening and HealingFactors

Since last update, I receive errors on startup. Furthermore, many buildings are not available in the Architect menu. Did something break?

Start-up log: https://hastebin-plus.herokuapp.com/xCe0bZBHYM
Output log: https://gist.github.com/HugsLibRecordKeeper/0abec649c7f28abf74ba5d8c6c3f690d

Disabling the mod (Stepping Stones) removes the error, hence the error must be caused by the mod.

Same error here. The mod RIMMSqol (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1084452457) has a problem with this research mod.

nchorbajian said in the comment section of that qol mod: Not necessarily a bug report but was there a reason to have the empty research tabs in the mod or was that for testing purposes? Those have started to conflict with the new research reinvented stepping stones update so I was wondering.
Here was a reply by Razuhl, creator of the mod: @nchorbajian The log just says that the author forgot to check whether the collection of projects is empty. You aren't allowed to pick the minimum if not at least one entry exists. The empty research tabs are there for people to group technologies so that they don't overlap or are out of the way when they are unwanted. Just plain vanilla xml modding nothing particular to my mod.

I tested without ResearchPowl aka a research tree mod and found out the showing of the organization researches is nowhere to be found (https://i.imgur.com/zUczIos.png); maybe it got placed too far to the left. As a result when I opened a save, there is no way to click the related projects for researching and unfortunately I can never build a wall for the rest of the save. Do wish it can be fixed soon.

...dammit, I fixed that four days ago. Turns out I forgot to actually *upload* the fix.

I mean I posted it in the comments section on this mod page too but didn't know if it was looked since it got swarmed by new comments :X

Thanks for the update today, @PeteTimesSix.
Still having issues on startup, though - and several items are missing from the Architect menu (thus cannot be built in-game): https://gist.github.com/0357014de4c005857f1e29e24e9c207c

I *have* fixed the wrong DLC check on those patch operations, so the fact theyre still in your log implies youre at least one version behind. Un/Resubscribe to the mod, that usually gets steam to actually update it.
Dont see any other errors though - just as a sanity check, several buildings that normally dont require any research are locked behind very early game researches with this mod (as of 2nd of November), is it perhaps that you just didnt research those projects yet? They start unlocked on a new game, but in an existing save they unfortunately need to be researched.

Thank you for your quick reply. For good measures I just un/resubscribed again... now it's fixed (sorry, thought I had the latest update downloaded already).
To answer your other question: Nope, I started a new game with Stepping Stones enabled form start, but thanks for the info.

All is good now.
Kind of you to fix this so fast. Your mod is a fine addition to Rimworld :)

Not 1.4 but Combat Extended one: Embrasures have no research prerequisites — should be "structures" project

It has been already noted in the comments section, but with this mod on, when right clicking on a item after clicking on a pawn, the game slows to a crawl. this does not happen in any mod except with this one.

theres a weird interaction wit this mod and alpha bees which kinda couples advanced honey centrifugation with another technology
I'll note it there too since I don't know which of those might be the cause
unfortunately got no save file or log since the savegame since then was corrupted

Good afternoon. Sorry, my English is bad, so I have to translate. I have a question. I use your mod with DLC BioTech. And if you make a fabricator robot, then he tries to learn everything, forgetting about tasks and blocking the work of all tables. Is there any way to turn this off?
And yes. The problem with fabricators also occurs without this mod, but only with Research Reinvented

Edit: I found a patch for those who play with this mod. I hope someone will need it: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2936760394
