World freezes for 10-15 seconds for every few ticks, spark profiler shows that the function EntitySunstrike.damageEntityLivingBaseNearby() is causing issues?

What other mods do you have?

Over 200... I'll do a binary search to find the incompatible mod in the next few days. It did not happen with the previous versions (Baraoko Chief) though

Do you have any Airships mods? Or Create?

I have the Create mod installed, no airship mods

I found the cause: Radium Reforged. After removing that mod the lag spikes are gone.
Would you happen to know exactly which function of Radium is causing this issue so I can disable that instead of the entire mod? https://github.com/CaffeineMC/lithium-fabric/wiki/Configuration-File
Thanks in advance!

Hmm I think I know what's wrong on my end too.

Try turning off entity collision optimization

Alright I'll try patching it on my end

mixin.entity.collisions
mixin.entity.stream_entity_collisions_lazily

I've disabled these two options, but the issue remains :/
