My girlfriend just starting playing with the last update (Alpha 5) and her steel stack stuck at 6 and started a new pile,
but the forge only registered the pile with 6 so she wasn't able to build the golden pickax and had to restart her game.
I also encountered a glitch in Alpha 4 where anytime I fullscreened the game it crashed. It started after trying to expand a third time
and I ended up playing the game in a small window. The glitch starts at about 1:54 in the video, here's the error log:
FATAL ERROR in
action number 1
of Draw Event
for object objGame:
instance_exists argument 1 incorrect type (undefined) expecting a Number (YYGI32)
at gml_Object_objGame_Draw_0
Still a wonderful game though and the glitches didn't deter my girlfriend from playing! (She did switch back to Alpha 4 though)
(New Edit: She also got trapped because she couldn't get around a furnace and didn't have any items to put in the furnace so she couldn't deconstruct it and had to restart)
