Viewing post in Mod: SfCArics
The last version that SfCArics was compatible with was 0.7.0a. There were changes made to the character generation system in the main game and I am having difficulties getting arics_body_parts to work with them. Technically arics_positions still works, and I have a working version of arics_races but I haven't released it.
