I get "Cannot register a generic event listener with addListener, use addGenericListener"
Forge updated something probably

I got the same issue. Here's the log.
latest.log

This should be fixed by updating to the latest ARL. Give it a shot.

Updating to new ARL does not fix it for me.

Can I get a log from the newest one?

Absolutely:

Pushing out a quark update, it should fix it.

The latest update of Quark and Autoreglib fixed it for me.

That fixed the crash. Thank you.

However, my regular garbage collection has now doubled. =/

Also, on a newly generated world, I get these uh ... gigantic round hollow pockets underground ... it's super weird. I thought maybe I added Better Caves or something. Nope. Just Quark, Optifine, and CTM. Then I thought it might be a funky seed but now I don't think so.

Is that why my GC & FPS tanked? I mean, they are GIGANTIC. I've never seen anything like it. This is my first time playing with a version above 1.12.2 ... so maybe it's one of these new world gen tools?? I didn't mess with them though. I've kept everything relatively default.

I'm having the same issue, even with the update you just put out and i have nothing on my server besides quark and ARL.

@Nessify did you update both ARL and Quark? Just making sure.

@WarlordWossman Yes, I did!

I'm dumb. I didn't update to the latest Forge. Everything is working perfect!
