When Minecarts are in each other it can cause MAJOR server lag

What MC version are you on, what version of the mod are you using, can you provide the mod list, can you profile the game using Spark when minecarts are in each other.

I can't do anything with this tiny amount of information.

Fabric 0.13.3, Fabric API 0.50.0, this is on 1.18.2 on the newest version of the mod this would happen when placing minecarts in each other

Latest version of my mod again tells me nothing. I've had many people who thought they were on latest, and were months out of date.

Also, are the minecarts connected, or just placed in each other?

placed in eat other and its mod version 1.5
