Pylons don't work in multiplayer

[ITHYAMP]

The pylon in the lost sea (calamity mod) does not work in my world. It worked in single player. There are residents, they are happy enough and live next to the pylon installation place. When I try to teleport to or from it, the map closes and teleportation does not happening. No error messages.

There are a couple of mods, including calamity and calamity vanities.

I found a similar question where they advised to remove the calamity mod fountain. I removed it, it didn't help.
