I played 2 worlds in the last 3 weeks and met the same bug.
I started with a SW world. the bioluminescences in the inventory were lost both times during the first travel into a volcano or to a ROG world.
However, they didn't disappear from the second travel, either to the existing volcano biome or ROG world.
One of my friend also confirmed the bug last week.
Steps to Reproduce
I used console to add the lost bioluminescences. Plz test this bug and fix it, very simple.
