-fixed legacy custom level check always being true (leading to stacked boss doors and a crash) due to a confused return type (was expecting string when return was a real.) You shouldn't need to fix your stage unless you moved the boss shutters in rooms, 17,18,20, or 21. Otherwise, levels no longer crash when you use their boss gates.

Last of the config file issues are resolved now.
-volume not being properly recorded in config file
-volume being defaulted to max for players with no config files, but after it would be defaulted to about 40%

-fixed a major crashed caused by a single letter that was invisible to me for three days because gamemaker shares configs between all versions of an executable compiled or downloaded. so global.input_pad_swapl being set twice while global.input_pad_swapr is never set. Would never have affected me unless i made sure to clear out my config file every run. because the bug was EXCLUSIVE to new players since version 2.14 , and no one reported it till 2.16B.
