--- Comment #4 from Paul Rhomberg <paulrhomberg01 at gmail.com> ---
Did more testing with this using less images that fill up roughly 300MB of video memory. Crashes have become more rare but are still happening. Right before crashes I am seeing low memory warnings inside of Xcode even though the reported ram usage from Xcode is even lower than what Construct‘s Debugger is telling me. This seems a bit inconsistent / weird to me as I can normally fill up the iPhones‘ ram to roughly 1GB without crashes, yet I sometimes get low memory warnings having all applications closed and the iPhone reportedly using very little ram. Crashes happen in a matter of milliseconds after the low memory warning, I assume there must be some kind of memory leak involved.
