Destroying and reloading sprites when drawing them causes a crash

[AlubJ]

I am making a font editor for a game, when reloading sprites it causes a crash when using ImGui.ImageButton.

After reloading, ImGui will try to render erroneous sprites, but uses the correct size from the correct sprite. I have double-checked my loading code, and the sprite references are correct.

Error:
