Error while running event RitnBaseGame::on_player_changed_surface (ID 59)
RitnCoreGame/classes/RitnSurface.lua:166: bad argument #1 of 4 to 'sub' (string expected, got nil)
stack traceback:

This is causing intsant crash with several character mods

/edit actually i tracked it with incompatibility with Hextorio mod, is there a way to allow compatibility?

Hi,
Thank you for the bug report. I'll take a look at it.
It's surprising that it crashes at the indicated line, but thank you for pointing out that the Hextorio mod might be the cause.

I'll probably be able to reproduce the error and fix it.

Could you tell me what other character or character selector mods you also use?
