I solved it.
This was not Playmakers fault, you just were standing in the room when Unity decided to do this.
Here's what happened:
1. Opened up Ecosystem, downloaded a script, script would not compile.
2. Editor is throwing weird 32:1:33 console error messages, no text or anything.
3. I think it's something to with my Ecosystem version or playmaker version, update that, the errors get longer.
4. Panic. Game is stuck, won't play.
5. I deleted all my playmaker / ecosystem stuff to see if that fixed it.
6. It's getting worse.
7. Time passes and I try to figure out the issue online, something about the compiler itself being all jank.
8. Find some random thread saying "don't open it up in HUB, just open up Unity Directly"
9. Fixes the console errors
10. In process of rebuilding my playmaker stuff I deleted in a panic.
It's always the HUB ruining my day.
