Texture Loading

Has anyone experienced any weirdness loading textures with beta22? I’ve had filetextures not updating their output when you switch strings, until you relink them, and today, a texture from a different texture node appearing as the output of another node…
No repeatable behaviour, but anyone else?

Also, having a renderer going to a dxtexture and using it on a second head seems flickery and sometimes stops working altogether… I use it for previews alot, not with video obviously!
