**Edit**  Ifigured it out.  It will only work if I manually add the token marker dead.  So when the creature dies I just have to open the token remove the marker and then put it back on. I installed Lazy Experience and did the config.  Have my players active.  D&D 5e OGL.  I have various scripts installed already.  I did NOT install death tracker but whenever I adjust the hp bubble for an npc to 0 it automatically puts a death marker on the token.  I do NOT get any message from Lazy asking if I want to add xp to the total.   Any ideas why that might be?
