Reproduction:

unable to apply a beaker of mannitol to slimeperson core with the tooltip "Squishy's core has decayed for too long, and has turned a sickly color. It probably won't work without repairs.
It seems to still have a bit of energy within it, but it's rather damaged... You may be able to restore it with some"

I tried to use a beaker of plasma, which would apply with left click, but then fail with "You failed to pour the contents of the large beaker onto Squishy's core!".

Tried to do the same with mannitol and mannitol beaker simply wouldn't "click" on the core. I tried to splash it and it didn't work either.
