Somewhat related is the fact that no textures under buildings will appear when model detail is set to 'Low'.

This still happens as of WC3 1.30.4 and Gem TD+ 1.5.4. It is rare, however. I have not found a way to reliably reproduce the issue. It is most likely...

Still happens in 1.31.1. And, yes, it is rare. General WC3 issue for sure.

Verify behavior in 1.32.0.14481, both for SD and HD.

Still happens in 1.32.0.14481 SD.

Still happens in 1.32.3. I'm pretty sure the ground texture under buildings can just disappear. May be related to use of Alt+Tab. Maybe even terrain deformations caused by various spells...

A potential solution is to hide/show the building. That seems to cause the game to refresh various things like the ground texture under the building. Need to pay more attention...

Another interesting notion is that if blocks were guaranteed not to happen, then I do not believe that creeps would need the ability to attack. In turn, this would mean...

Of course, that does not mean that creeps will not become confused. Because of this, issuing a move order periodically to them may be something to consider.

At the very least, an improvement to the existing block behavior could be implemented.
