Got this problem too since build #184 (1.16.2)
Actually on: build #191 (1.16.3)

[ikuria]

pls fix that issue - we need motion!

[aikar]

1.16.2 is now end of life, so if you for some reason can't update to 1.16.3 you will have to go back to 183 instead.

Def would be caused by that change, so will look at getting it fixed.

[J0schlZ]

We are on build #191 (1.16.3) as i said.
The issue is still present in this build.

[aikar]

yes we have not fixed it yet hence this being open still. I was just commenting that 1.16.2 will not receive the fix, so you have to update to 1.16.3 to get it fixed once the fix lands.

We really don't need the pointless bumps on this ticket, it's a known issue and will be fixed when somebody can get to it, your timeframes are 100% irrelevant to us; You're more than welcome to revert the offending commit yourself
