The rename feature does not seem to be working. When I click on it the radial wheel disappears and nothing happens.

I know, I noticed this also... will look into it .. there seem to be a bug making it not renaming...

The fuel cell engram is not working, the one part not showing is dinosaur feces. We have collected all types of feces, but none of them fill that "Dinosaur Feces" slot.

It's been using an older version of the feces no longer used in the game. The recipe has been changed and is updated in the next update hopefully out tomorrow.
I'm sorry for that

Thanks for this mod, been using it for a while and we love it. Odd thing is happening though, as of today 3*28*2018 no one on my server can place one of the plots down. It's green, makes the sound effect of being placed down....then it vanishes and reappears in player inventory. Any suggestion would be great....(the only change I made is two days ago I added the popular flying mod. I even tried reverting (deleting ) the flying mod, but the issue persists.) Any suggestions would be appreciated.

TBH both my servers crashed this morning, so I can't replicate this atm. I will get my servers running, and then try to replicate this. Usually when it get green, but you can't place it it suggest a missing file from the mod.. I find this unlikely, as you have been using it before. Could you please try and remove the mod, delete all the files from the server, and then re add it ?? note: BEFORE doing so, please tell your players to remove any items in the plots, as all will be gone when you do this.. This is to ensure atleast all of the mods file are installed. I noticed alot happened now in the latest patch of ARK, and I am trying to figure out what has changed in the gamefiles and how the game read things.. ( not core files, as they are left alone )
Do you run any Core changing mods? Like Extinction, Annunaki, Steampunk or any like that?
