When a player enters weeping_well, it bugs and no longer allows him to enter the server, the stack trace would be as follows.

This is just another serverside particle crash, it's already fixed on the dev branch, but I found some rendering issues I'd like to fix first before releasing anything.

thank you so much, we can wait for it i hope doesn't take too much. I opened another issue with a detail with a totem, I don't know if it is also identified.
'Crash in a Server when do 5 arcanus spirit totem #194'

Yeah these are all the same issue.

Fixed in 1.5.0.1
