yes, easy for frozen example:
((L2PcInstance)target).shortBuffStatusUpdate(1056, 1, 15);
put it after
ThreadPoolManager.getInstance().scheduleGeneral(new CustomCancelTaskManager((L2.............
example:
if (cancelledBuffs.size() > 0) {
((L2PcInstance)target).shortBuffStatusUpdate(1056,1,10);
ThreadPoolManager.getInstance().scheduleGeneral(new CustomCancelTaskManager((L2PcInstance)target, cancelledBuffs), 10 *1000);
}
