Error loading mod: LinkedBelts/data-updates.lua:25: attempt to index field 'sheet' (a nil value)
stack traceback:

Modlist? (space-age, etc are also mods)

This is mainly for testing, as I think I already know what went wrong, but won't have time to fix it for the next month.

I have a fully updated Space Age plus another 150+ mods.
If you still need me to list them all, i will gladly provide a list somehow.
Thanks for your time!

I have same error, after add mod:
