Issue with powexec_location target macro

[Lost Cosmonaut]

I use a powexec_location target macro for Tar Patch that usually works great, but I've noticed that once in a while the power fires but there is no Tar Patch around my target.

 

I've figured out that it IS dropping on my target, but at whatever the lowest location is at their feet.  So if they are on the ground it works correctly, but if they are on a second level like in a warehouse map, it will drop on the 1st level instead. 

 

I'm not sure if this is a known issue or not, I searched around but didn't find anything on it.
