Topology not working after copy / paste

[big_b]

I just tried to copy paste about 24 boards using Classic Surveyor in build 129343 to extend an area. Pasted area in red
The copy / paste went fine everything a perfect copy but it broke Topology
Nothing works I tried to change heights etc and all it does is add grass .I've tried this twice now with the same result

I had that happen once in TRS19 but it never happened again. My fix was to click on one of the other tools such as get height and that fixed it.

I've had the brush disappear with textures in a similar fashion. Clicking on one of the textures, or the same texture brought back the brush.
