Could you post your log after encountering some of these issues? I reckon there'll be some juicy errors in there. ;)

Here is the end of the log file, I omitted it loading previous files to the campaign because there are so many but let me know if you need them!

Hmm, interesting. Looking at the code it's not immediately obvious what's going wrong. I'm going to have to run this at my end to get the full picture.

I assume this custom map is not on the workshop yet? If so, would you mind sending it over to me at support@twicecircled.com? :)

Sure thing! I will have to send you the whole modpack because it uses a modded theme and some modded fish. :) Also, as a note, I copied all the map settings (everything but the map itself) into another map that is also using a custom theme and the same modded fish and that one works just fine.

Hey! Just wondering if you had any updates on this, Tim. I sent this over a while ago through the email and didn't get a reply back. I'm sure you're busy so no pressure, it's just been a while so wanted to make sure you hadn't forgotten!

Hey Flishster, I'm sorry, yes I did receive it, I should have replied. It's on my to-do list, I'm currently working my way through the bigger features for the next update and then I'll work my way down the list to issues such as this.

Apologies for the delay! I think it's really cool that you're working on a custom scenario, definitely want to support this. :)

Alright! Thanks for letting me know!

seems to have fixed northern_plunge_iceway.sav with:
1) nextUID = 886 (probably main issue)
2) adding 2 items to unlockedSpecs
3) correcting the counts in namenumbers

Nice Map!

Thanks for the help again Stlnegril! Hopefully this will help anyone else who gets this problem in the future.

Oh interesting, yes, if you are manually editing the map via text editor and adding objects, then nextUID needs to be higher than the uid of any objects you've already got in the map.

Basically every object gets given a unique id (UID) when it is created. The next id given is the value of nextUID and then nextUID is incremented by 1.

If the value of nextUID is less than a UID that is already assigned then the same UID will be assigned twice. This is likely to cause errors.

Nice spot Stlnegril.
