Overview
The swell value of creepers, i.e. how close they are to the explosion, is not written to NBT. This means a creeper will never explode if it is constantly saved and reloaded.
Additionally, this is inconsistent with the maxSwell value (NBT tag Fuse) which is written to NBT.
How to reproduce
Summon a creeper
Ignite it using flint and steel
Just before it explodes close and reopen the world
Alternatively sending an ignited creeper through a dimension resets its swell value
Outcome
The creeper does not immediately explode but instead starts to swell again

Ty.
I'm glad I did not make a dupe.
I checked like 4 to 5 time 😛
Hope it gets fixed in 1.16 lol but they do have a hell of a lot there doing.
I have reworded your report to describe the underlying issue a little bit more, otherwise it could have been considered a duplicate of MC-75045. I hope you are fine with this.
