Massive memory leak in Blueprint Editor introduced with Unreal 4.9

4.9 didn’t have this problem, 4.11 eats memory, the more you use it the more it takes and never frees. I usually worked around 2.5 gb, but 4.11.1 reaches 5 easily with the same project. And I believe it increases even more but I usually close it to have the system freed (since I’m having 8 gb system). Not sure what could cause that because I’ve never used 4.10 and I can’t confirm it had happen there. Another thing I observed is the built exe when ran outside unreal does something similar. Usually it would stay within 1gb usage but now it reaches 2gb sometimes.
Each time it passes over 5gb, closing the editor doesn’t close the process also, even if I’m waiting for a few minutes, most of the time I’m just killing the process from task manager. Sometimes if I let it long enough will stop the process as well but it’s not really normal.

Same here. Editor almost killed my system twice during a gamejam…
