ALRIGHT, CAN SOMEONE RESOLVE THIS ISSUE?
It turns out that I'm an idiot and left my game on peaceful while testing something during the night. So, this report is INVALID. However, I have had this issue previously on my survival worlds, so maybe if this happens again I will report it properly.
I have this issue too, and have a video. However, with me, the issue persists even when using other forms of lighting TNT (flint and steel, lever, etc)
Can confirm. Happens to me all the time. I have no idea why.
Happens on my 1.14.2 multiplayer server all the time.
