Unable to re-stack radioactive elements

[UltPokemonFan]

Hi. Not sure if this is a bug or intended. Anytime I split a stack (any size) of radioactive elements, using right click, I can't stack them back together. Why does this happen?
Minechem version 1.7.10-5.0.5.406

do they have the same NBT Tag Data (Such as Half Life countdown)? if the NBT Tag changes, it would refuse to stack obviously because it's no longer identical. perhaps they might stack again if you throw them all on the ground? ( assuming they are in fact identical)

Um... heh... that was a long loooooong time ago. Uh, from what I vaguely remember, I doubt they had identical data. Maybe splitting the stack changes the decay time slightly? Idk sorry.

that was my guess too, I was guessing a 1/20th Second (1 Tick) Difference. at least if anyone else encounters this problem, they have this bug tracker to refer to.
