It's a bug.I do wonder if this is a bug
I experience it at least once at recalc when I play GvG.
There have been bugfixes for GvG in the past. I guess you're referring to the issues that only happen when the maps are busy?Although the thread is marked as "reported to developers", there is little hope this will be dealt with in the first place
Anyways, not part of this topic, really
