I was playing in full screen mode (and yes this has happened at least twice) and I placed a house
and 4 errors popped up
they said
" lua line 59, bad frame transition start to stopped" (same for each)
I didn’t screencap it due to my laptops strange printscreen functionality and the fact that I was in full screen
my laptop is a high end windows 8, Qosmio Toshiba X870 laptop with a very good nvidia graphics card (geforce gtx 670m) and i7, quad-core processor. with 8 virtual processors.
The game usually runs at 80/100 fps for me, and with vsync on it is constantly 60.
I tested it again and got the error a second time, it only appears in full screen mode.
edit:
played again
Got on my first house TWICE
It seems to happen often.
