The BepInEx console will not appear when launching like it does for other games on Thunderstore (you can turn it back on in your BepInEx.cfg file). If your PEAK crashes on startup, add -dx12 to your launch parameters.

A mod for PEAK that enables the enabling of multiple cosmetics at a time, syncing with other online players who also have the mod. Shouldn't conflict with most custom cosmetics.

"why are my friends bald"
Due to weird sync issues, sometimes your friends may appear bald when you/they join a lobby. I don't know how to fix this but it doesn't cause issues. Just equip your items again and they should stay put!!
"my friend is being lame and doesn't want to play modded"
That's fine! Tell them they're lame, but this mod doesn't explode when you play with unmodded clients. The item that appears for your unmodded friend will be the last thing you clicked in the passport. It might be confusing, but it's their fault for playing unmodded.
"i keep seeing 'weird thing', are you going to fix that"
Maybe! Probably not. If you're a part of the PEAK Modding Discord, you can ping me (Spider) in one of the channels and I'll probably respond with some advice and/or a 50/50 "i might fix this, i might not".
"wow this is cool how long did this take to make"
A little under a week, now.
