Bug Hitting entities/using binds/opening chests etc

[Leeness]

Now, i'm almost 100% sure this issue isn't on my shitty lag ^_^
*Using binds that are bound to right click sometimes do not get used the first time clicked. And need to be clicked again. (was trying this with skill light bound to pickaxe).
*Opening chests/furnaces/benches does not work sometimes, as in it's like I have not clicked anything. However my arm swings. I need to right click it again.
*Hitting entities whether it be mobs/animals/players is extremely hard, (mainly on mobs because I do that a lot) as I cannot hit them a lot of the time. Even if they are up against a wall, stuck in a 1x1 hole. I need to spam hit for it to be able to finally register or keep changing the angle of my shot while hitting. Here's a video of me trying to hit dils1 while standing still.

I put all three together as they all hold a similarity with each other.
I didn't think it was lag because on all previous maps I have never had this issue.

I've never had an issue with issue #1.

I have noticed issue #2 occasionally.

Issue #3 seems to happen for me a little bit too mostly on mobs not players, though not as bad as what your video seems to show (probably due to the difference in lag).

Probably because I spam my binds so often I've only noticed it on the light skill, then again you have that skill too. Hmm. Glad others experience this. I'd say #3 is the most important. Happens on mobs a lot more than on players for me, too. And you think that video is bad I believe Dils1 has experienced this too.

I've seen the first one happen, but extremely rare.
Second one happens daily.
#3 happens now and then, often based on my internet speed(I usually play with 400+ ping).

I hit players all the time and get the crit sparkles, but no damage is done to them. x(

I have had some trouble with issue #1, but mainly when the server has quite a bit of lag

#2 I cannot recall having happened to me

#3 Actually happens to me a bit, it wont even register my hits sometimes, no matter how often I click

Quite certain this is due to an anti-cheat system in place, I'll look at adjusting it.
