My version of aCis is 382, so I don't have these variables in my review. However, I changed the intentions to synchronized, which already improved part of the process, but unfortunately it didn't fix it. I also checked version 401 to see if it contained the _isAttackingNow variable, but it doesn't either, and moveTask is a complete class, meaning it's not possible to change just one method, unless you're talking about the moment the task was created. I really need help with this, I've been dealing with this for months and haven't been able to resolve it, and it has a huge impact on the gameplay on my servers. This way, if anyone is interested in helping me, I am willing to resolve it.
@edit
If i have to change my aCis version, that is not an problem.
