Throwing spore puffs breaks my game.

[catpop12343]

I have a lot of mods installed. One day, I was playing around in arena mode when I threw a spore puff and my game broke. I was able to press the exit button and restart that round, but it keeps happening and it's getting annoying. I decided to test something and deactivated all my mods, including the ones that came with downpour. Do any of my mods break spore puffs?
My mods are:
- Solace (aka The Friend mod)
- Move testing rooms
- Slughoodie
- The Outsider
- Rotundworld
- Visible ID
- Bubbleweed shortcut
- Open exclusive region
- Rebind artificier
- Music announcements
- The Vanguard
- Nutils
- Serene Grotto arenas
- Alternate slugcat missions
- Substation epsilon
- CanonRivulet
- Beastmaster pup extras
- Simple customization
- Caterators!
- Dress my Slugcat
- The Sporecat
- Catsupplement
- Thicc spearmaster
- Diverse shelters
- Regionkit
- POM
- Needle cleanup
- Emerald's tweaks and features
- Watch Your Aim
- The Dronemaster
- Seaside Level Pack
- Firmly Grasp It
- Omnithrow
- Fisobs
- Testing arenas
- Beastmaster
- Friend of friends
- Immortal pups
- Pups for everyone
- Rideable Lizards
- Slugbase
And the mods that came with downpour (Devtools, Expedition, More Slugcats Expansion, Challenge mode, and jolly co-op)

Any help would be appreciated!

The Outsider is the most likely culprit as they die when exposed to Sporepuffs.
Or Sporecat, iirc it isn't updated to match newer updates.
