Hi. I got a strange error saying the mod is not multiplayer safe, something about an event handler not being registered properly. Here's the relevant excerpt from the log file:

42898.853 Error ClientMultiplayerManager.cpp:1092: mod-tile-upgrade-planner was not registered for the following nth_ticks when the map was saved but has registered them as a result of loading: 1
42898.855 Error ClientMultiplayerManager.cpp:85: MultiplayerManager failed: "" + multiplayer.script-event-mismatch + "
" + "
mod-tile-upgrade-planner"

I was only able to clear the error by restarting the server.

Should hopefully be fixed now

Seems like it works! I wasn't sure the exact circumstances that caused it, just that it happened on reconnect, so I'll let you know if it happens again somehow. Thanks for the quick fix!
