[Solved] Errors from updating a mod to Alpha 4F

[Argain]

I was trying to update my Rimrats mod from Alpha 3 to Alpha 4F, which was a very simple replacement of the 'using' statements in the assembly and a few minor changes to xml defs, but when I tried to run the updated assembly it started throwing odd errors:

It's odd because my assmebly makes no references to the old 'UI' namespace, let alone any of the classes that are supposedly not being found... and as soon as I remove my mod from the folder, everything runs smoothly again

Here's the complete assembly:

Nothing about any 'UI' stuff in there... so yeah, I'm stumped.

Those are all regarding the inspector tabs that will be held in an .xml file. In the Core mod, these are found in /Defs/ThingDefs/Races_Various.xml in the BasePawn thingdef. They will most likely be held in the .xml file you've got that defines the rimrat that will be in the /Defs/ThingDefs folder of your mod.

[Argain]

Thanks! Got the UI errors all cleared up... just one left:

Could not load class AI.ThinkNode_ConditionalRimrat, RimratMod from node <thinkRoot Class="AI.ThinkNode_ConditionalRimrat, RimratMod"><subNodes><li Class="AI.ThinkNode_Priority"><subNodes><li Class="AI.JobGiver_Curiosity, RimratMod" /><li Class="AI.JobGiver_WanderAnywhere" /></subNodes></li></subNodes></thinkRoot>

I know it's gotta have something to do with the .xml file again, specifically the SubThinkTree... but this is also stumping me. It's virtually identical to the way the Core is setup.

SubThinkTree_Rimrat.xml

If you remove the ", Rimrats" parts, it should work.
Alpha 4 doesn't support the Assembly references anymore. But without them it should work.

*facepalms* yep, that was it! Thanks a ton
