Death issues

I applied Health Boost 255 but then it wore off and I "died", but I instantly became alive at the same spot, as if I wasn't dead. Also, when I press "e" into my inventory my character acts as if its in a dead position.

Steps to what happened:

• I applied Health Boost 255 for 255 seconds

• I went to almost max hearts, but 1 bar of health less.

• It wore off and it showed me the respawn screen, and

when I pressed respawn it was like I never died, and the

inventory is a little messed up.
