Since the launch of GW2 this has been an issue in WvW, especially for roaming players. The moment a dolly is being speed buffed client and server information desynchronize, unless you witnessed the speed buff process from the beginning.
It is a problem, if you want to take out a dolly, that is being speed buffed. Because the attacker has wrong information of the dollies location, one is not sure, where to actually attack. If you manage to CC the dolly (soft CC such as fear seems to work, as well as dazes and stuns), the dolly jumps from the attackers perspective to its correct (server side) position.
When the dolly is escorted by a group of player, one needs to take it out and get out of there immediately. This is but not possible in most cases when the dolly is displaced. Please fix it.
I’ve seen this happen before quite a few times and it is indeed annoying as hell. I hate it.
