Cleaned up my files, downloaded the newest version and applied the script. Hope that fixes all problems.

I think another update may be in order. I'm trying to use this, and currently get a lot of duplicate traits. Anyway to confirm that this issue just isn't on my end?

Perfect, thanks a lot :D

He fixed it and I updated this mod.

Thanks for the info. Gonna update as soon as gwen is fixing a bug in his mod that breaks my script

Hey Gratak, just a heads up, since Gwen's mod has been updated this compatch will need a small update too :)

Updated mod.
1. While I do not like spaces in identifiers and would never use them myself, I have updated my script to recognize them. Pretty sure this issue is fixed.
2. The only reason I can think of why this can happen is that upgrades are missing requirements. Added copying up requirements from the base building. Hope this fixes this issue.

Two issues:
1/ building icons are broken in a number of files. I checked the files and where it should be icon = "building building building" the spaces have been replaced by line breaks, thus breaking it. I noticed it in the subterranean buildings file but might be more widespread
2/ you can see all the buildings regardless of traits. not so much of a problem for the subterranean buildings because you can't building if you don't have the cave world modifier, but in my current game I could build a cold blooded heat collector for my human empire just for kicks.
Cheers
