got a crash when i start a new game or load a save ( not the game but a save!)
with both mod enabled.

Error while running event ColonyBuilder::on_configuration_changed
core/lualib/production-score.lua:50: table index is nil
stack traceback:

In the colony builder mod discussion :

It's due to Cerys' use of https://lua-api.factorio.com/latest/types/ResearchProgressProductPrototype.html

https://mods.factorio.com/mod/ColonyBuilder?from=search

Thanks for the thread. Cerys is using a new game feature, so this is essentially a 2.0 compatibility issue with Colony Builder.
