0.6.17 Crash When Alt+Tab At Start of Master Battle

When I alt+tab as I am about to begin a master battle, the game crashes.


############################################################################################
ERROR in

of Other Event: Room Start

gml_Object_obj_resolution_Other_4 (line 79)

Thanks, fixed for the next patch!

The crash has been fixed, but now it shows a black screen instead. Presumably, the battle is still occurring as I can hold E to use my macros and the battle ends, but no graphics are displayed.
