Hello guys, We are pushing new update to EXP branch, yeeey! This is very important update for us.  Update 0.61.137302 contains: Potential fix for a crash caused by players based around locking the hands slot. Server performance optimizations regarding stacking of some AI related data. Security measures to address known issues. Melee weapon behavior tweaked (impact now on cursor). Tweaked torch lightsource position. If it works without issues we will push it on Stable as soon as possible.  And we need your help.  We are interested in two things, both of them connected to locking of hand slots during actions (executed from action menu), which have an animation - e.g. during the animation, hand slot should not allow manipulation such as removing of item if there is any or inserting if there is none. So inserting/removing but also swapping. a) during an action, try drag and dropping or swapping items in slots - try to get them there. Even if not successful and the item stays in its original position, try destroying it during the action (e.g. tear shirt into rags) or moving it - it is possible that after the action/animation is finished there will be some issues. If so, we are interested in knowing what was the player doing right before that. b) after finishing the action, or cancelling it (by pressing F or by right-click to another item in the inventory), it is theoretically possible that the hand slot will stay locked. If that happens, we would like to know the chain of events leading to that state.
