Fatal Error during "3 hard 4 you" dungeon. Thread - Hashtag Dungeon

A short one, as I'm afraid I don't know the cause yet.

I've just installed the latest version, had a go on the "3hard5you" dungeon, and fought my way up a few rooms. I'd just beaten the room with the purple diamond enemy in it and entered the next one; from what I see on screen. it looks like the last room of the dungeon? An enemy began to spawn in at the top centre of the room, but the game crashed before they actually appeared on screen, with just the purple smoke displayed. The following "Code Error" message appeared:

###
FATAL ERROR in
action number 1
of Step Event2
for object obj_Col_Parent:

Push :: Execution Error - Variable Get -1.Speed(100118, -2147483648)
at gml_Object_obj_Col_Parent_Step_2
###

I've retried the dungeon several times with slight variations (going directly there without exploring first, choosing the other playable character) and the game crashes at the same point each time, with the exact same error message.

Following on, I've found the same error in one of the rooms close to the end of the Leviathan dungeon; the first enemy that spawn, one of the weird masks, spawns fine, but the next enemy causes a crash with the exact same error message as above.
