Multiplayer issue

[raistlin]

minetest version: 5.2.0
whynot version: latests published on ContentDB

I play with a friend on a server hosted on my PC, when he leaves the game, the game crashes.

Can you provide the crash output from debug.txt for the crash?

I reproduced it:

It' seems to be craftguide mod.

EDIT: Missed the SackTrace

[bell07]

Seems you enabled the craftguide_progressive_mode in your minetest.conf.
That's is not supported, because the whynot game uses own doc-mod based progressive mode (craftguide_reveal mod)
Eather you disable the setting or you remove the craftguide_reveal mod.
The benefit of craftguide_reveal is the items reveal status is in sync with revealed documentation.

Thanks!
