Dalph, it's been stated already that the Devs are aware of the memory leak.
You misunderstood, I didn't say there is no memory leak in my previous post, I just asked him to prove me if the 50 maps will cause the same effect as in his example. The devs said there is a memory leak, but it's not as bad as he claims it to be. The effect is not as disastrous as in his sample project, you would need to play a game for over 15 straight hours to start seeing it (and yet it won't be as bad).
What I was wondering is, how is this even affecting his game dev? Unless that dude has his game on 24\7 I don't see this being a huge problem at all.
Anyway, I'm out of this discussion.
