issue happened after the update this morning, for 0.3.4

error reads:
Failed to load mods: OCs_base_assets/prototypes/utils/helper.lua:605: attempt to index field 'debug-mode' (a nil value)
stack traceback:
OCs_base_assets/prototypes/utils/helper.lua:605: in main chunk
[C]: in function 'require'
OCs_base_assets/data.lua:3: in main chunk

This is likely to be caused in combination with another mod using the same "debug-mode", I guess. I cannot reproduce it, but it should be fixed with the next update.
