I am also getting the crafting crashing. Running on an Asus Zenfone 5 (android 4.4, 2gb ram, one of the older ones with an intel cpu rather than qualcomm).
Looks like it is struggling to load all the images. Anything already in my inventory is there, rest of pictures take a long time to appear and I can do nothing til they do. Almost guaranteed to crash if i switch to another tab.
Might just be hitting the limit of my phones processing power idk (this thing has seen 18 months of pretty heavy use), might be fixable by optimising code a bit.
Also- unrelated issue. Not sure if this is new or just un-noticed by me til now, but I'm turning round to place furniture behind me, which gets awkward. If I want to place a left-facing chair with it's back to a wall I have to knock a hole in the wall, stand so I'm half out of the building and place it, then put the wall back. Right-facing stuff is ok, I can stand in corner and place it on myself.
