memory leak when updating tiles?

[kyunghoon]

Bevy Tilemap version
0.4

Operating system & version
MacOS 11.3

What you did
tried to update tiles using Tilemap.get_tile_mut(..)

What you expected to happen
expected the memory usage to remain flat (~80 MB)

What actually happened
memory usage slowly grows and grows (2 GB and counting), visually looks correct.

Additional information
if i comment out the single line of code that does the modification, the memory issue goes away.

Huh, thats interesting. I hadn't noticed that on my end but clearly, it appears to keep grabbing the tile mutably ... ? Should be only updating the one memory position. Shouldn't be making copies of it without dropping it, as per how Rust typically works. Do you have a more specific use case that could possible be doing something odd?

I can confirm the memory leak on tile update. Haven't found a solution yet but still looking.
