At the moment I have to agree with PikaDude completely.
I have been reporting the following bug on GitHub and I even mentioned it much earlier via the discussion section on here and just now brought it up on discord AGAIN:
https://github.com/Drawethree/PRO-DeathChest/issues/9
It's probably the easiest thing to implement but nothing has been done for MONTHS even though I'm paying actual money for this plugin.
Issue has been resolved after a long time so I'm changing my review to 3 stars instead of 1
What PikaDude said about the verification system is also true, leading to more frustration.
I also just found out that if you die due to using a bed in the nether and the explosion from that no chest spawns at all which only lets you access this "chest" (which is not present) via the remote way described before.
