"Cannot join. The following mod event handlers are not identical between you and the server. This indicates that the following mods are not multiplayer (save/load) safe."
The log file shows this:
" 57.912 Error ClientMultiplayerManager.cpp:1080: mod-cardinal was registered for the following events when the map was saved but has not re-registered them as a result of loading: on_tick (ID 0)
57.912 Error ClientMultiplayerManager.cpp:85: MultiplayerManager failed: "" + multiplayer.script-event-mismatch + "
" + "
mod-cardinal"
"
The server added other mods since last time I joined, but the other guys playing on it are still playing just fine.
I tried the usual suspects of deleting/resetting the mod(settings) etc, so not sure what to do

Any ideas?

Edit:
Deleting me from the server/save also didn't work. Investigating...
Rebooting the server fixed it.
Not sure why it was an issue just for me specifically, but at least the oldest trick in IT solved it ;)
