As discussed previously on IRC, I suggest to remove GUI access to the following options:
* Path finder selector: Unfortunately Silnarm's path finder has not been working for us for a while now and it has not been worked on for a while, so at this point it is just an option which will cause crashes, and should thus be removed from GUI. It can remain as an .ini file option, though, so that it can be worked on again later if someone gets around to it.
* Server controlled AI: Client controlled AI does not work too well and has been causing crashes in the past, but server controlled AI works very well. So I recommend to remove GUI access to this option. If, for any reason, client controlled AI would seems to make more sense in a certain use case, it can remain as an .ini file option, though, so that it can be worked on again later if someone gets around to it.
* Shadow mapping: This option does not seems to work for anybody - it seems to always result in a message of "GL_ARB_shadow_ambient required for shadow mapping". So it seems to either rely on an OpenGL extension which is not available in nowadays hardware or it just fails to detect availability of this extension properly. In any case this option is not usable for anyone. So I recommend to remove GUI access to this option - it can remain as an .ini file option, though, so that it can be worked on again later if someone gets around to it. Alternatively, it might be possible to try and fix shadow mapping. Thanks to kobe for pointing this out again recently.
