Current Behavior

I was on level 4 of the Composter's Hut using the Fairytale style pack. I have had no issues with any other building or level. For some reason whenever I specifically go to upgrade the Composters hut to level 5, the game crashes completely. I went through and went in creative mode in order to paste the level 5 version of the hut and paste it constructed so it can be functional, however, any time I click "Build options" on the level 5 or anything that has to do with getting it to level 5, it crashes. I tried in both create and survival mode, I have destroyed the building and re-built it, and it still crashes at that stage.

Expected Behavior

I expected that like all of the other buildings, it would open the menu, and I would be able to select a builder, and upgrade the hut as usual to the 5th level.

Reproduction Steps

1. Use the Fairytale style pack for your colony
2. Upgrade your Composter's Hut to level 4 going through each level the organic proper method using builders
3. Once you're ready to upgrade to level 5, go to the hut, and click build options
   OR
4. If you have already schematically placed the building in level 5 from creative, go to the composters hut, and click build options
5. The game crashes from there
