So with the new analytics tool I get the errors and warnings directly reported to me 
For the last day I've been getting some reports about this:
Error!
---
Function:
D3DTileTexture::ThreadBuildTexture
Message:
Texture 'media/entities/particleTypes/particletextures/smoke2.png' has incorrect dimensions [256x256]!
The correct dimensions should be [252x252]!
This is reproducible by changing the texture quality in the launcher to the lowest.
Added to the list of Bugs/Issues & Crashes!
