I'm playing Solasta in multiplayer with a couple of friends, and we noticed when looking at the proficiency tab of our characters that all skills are in the negative. After exploring this issue a bit, it seems like every single character has this issue: Pre-gen and custom, characters that are active in a campaign and have levelled up, characters that were never played with, in both singleplayer and multiplayer.

I'd be happy to provide any further information needed.
