Load puzzle: 1766: 590.064 Kb

repeat another 10x
load current from quicksave 1: 776.688 Kb
another 10x
load current from quicksave 1: 872.144 Kb

After some time, the client reaches 1384.985 Kb
one shake adds 50.000 Kb,
wiggle ads another 50.000 Kb.
Eventually this will crash the client around 1.8 Gb.

No other processing took place.
Clearly a memory leak. Please solve asap and repost puzzle 1766 soon.

Same problem here with windows.

See also crashes on puzzle 1766 TIM barrel redesign.

Just adding this code near the start of a recipe may be beneficial:

undo.SetUndo ( false )

On 1766, it seems to eliminate the crashes, limiting "peak private bytes" to a more reasonable value. (Relatively speaking.)
