Infinite Error in Image.cpp

[JoshOClock]

Hi,

I'm getting a fairly frequent error log that Unity fails to recover from.

It's essentially this message over and over again:

The only fix is usually to start deleting my compiled sprite atlases, re-launch Unity and then resync the atlas. This worked a few times as a quick workaround.

However, I seem to be hitting this error a few times a week now, just wondering if there was something I could do about it?

This is really strange, can't say I've seen this error before. What version of Unity and 2D Toolkit are you using?
Also what format is the atlas texture in when this happens?
