The game threw an error when updating from version 1.0.3 to 1.0.5, and I encountered the same error after manually rolling back to 1.0.4... Should I report this to the Reverse Factory author?

kry_stdlib/stdlib/data/technology.lua:177: attempt to index field 'unit' (a nil value)
stack traceback:
kry_stdlib/stdlib/data/technology.lua:177: in function 'multiply_cost'
reverse-factory/prototypes/reverse-factory-updates.lua:37: in main chunk
[C]: in function 'require'
reverse-factory/data-updates.lua:2: in main chunk

I compared the differences between version 1.0.3 and 1.0.4 and found that version 1.0.4 removed the optional dependency on ​planet-muluna, causing the ​reverse-factory​ mod to throw an error. However, even after removing ​planet-muluna, the error persisted. Eventually, I used the process of elimination and found that the culprit was ​AAI Industry...

If I add back the optional dependency on planet-muluna, the issue is resolved. What a recursive problem this is...

the optional dependency fixing things kinda makes sense as it changes the mod load order

By default, the Exotic Space Industries mod includes some KR2-related content. If you have modding experience, you'll need to manually edit the Lua files and comment out the KR2-related sections in Exotic Space Industries to make them work together.

If you can't edit it yourself, you'll need to contact the Exotic Space Industries mod author for help.
