Rock Crab bug
A rockcrab is a agressive monster. When you are in fight with one of the rockcrabs and another one attacks you because he is agressive it will walk under you instead of next to you , making it harder to attack it and more click intensive.
Ancient staff bug
I am not sure if this works with all the staffs but if you wear the ancient staff you cannot see your combat level anymore. Instead , there is a question mark.
Aberrant Spectres bug
In the slayertower Aberrant spectres are agressive. They can attack through the walls.
The slayermonster bug
Some of the slayermonsters within the slayertower have a attack bug that when they attack the animation is totally fucked up. For example Banshees.
Burying bones bug
When you bury bones and click right after for burying the next one it will not work until you have done another action (for example attacking a NPC) and then it works again.
Pick up item bug
When you have killed a monster and you right click the item you want to get in your inventory it does’nt always pickup the item. Sometimes u have to click it more times. This happens alot when you are safespotting and click it from a distance.
