I'm having this stick issue as well. I have stickmode=o with stickrange=60. That is how I have been running for years. Yesterday it seemed like I had to unload/load MQ2Melee several times, along with MQ2Moveutils, to get it to start working. Today I tried unloading/loading MQ2Melee only, which didn't help until I did that while in combat. So, I'm not exactly sure yet what sequence/situation of unloading/loading MQ2Melee is correcting the issue, but there's definitely something wonky with sticking through MQ2Melee.
