Hello,
Yesterday, I downloaded the latest version of C2 and I exported my (currently developing) game for PC using Node Webkit for testing purposes.
The game was randomly freezing for no apparent reason - It would freeze for about 2 to 3 seconds then continue as normal.
At first I thought it was a RAM issue - but I do indeed have a good amount of RAM and less that 40% of my overall RAM was being used.
I plan to have my game released on STEAM February 2015.
I hope that this problem is fixed before then - a game that's freezing up on STEAM would be ...... embarrassing.
