Playing the skyfactory 3 pack, guy opened giant chance cube and when we were hit, we both were crashed to the lobby. I dont know what kind of info i can provide to help you with this. Probably a bad potion Id somewhere.

I wish i had one, im playing on a server so i dont have access to that info. The client doesnt crash so i dont have a crashlog i only just return to our servers lobby where we pick the modpacks. Would such a disconnection cause a error log or crash log i could have the owners send me?
It may not even be a problem on your end but i dont know how your mod works when it uses that potion shower, but it may help someone else in the future if we can figure it out.

The crash/ error log would help greatly!

Update, seems to be a HWYLA bug. Anyone reading this with the same problem i had, update it then try it, or disable HWYLA until the bug is passed. If it still bugs when its disabled, try to move quickly as soon as your game loads. Please close this issue and thanks for taking a look at it.
