I play on a direwolf 20 server and once the crystals are grown they despawn. This can be an issue if you are not constantly check the crystals and because its at the beginning it takes longer for them to grow without the accelerators so I often leave the server(I have a chunk loader) and when I come back they are gone. It is not from players as it is covered for that reason. Please fix this issue to make them not despawn until picked up.

@dovahkiin4991 most certainly a problem of the server owner using some sort of plugin or mod that despawns unused entitys to prvent lag (nolagg f.E.) try to blacklist the items in the config of the tool or remove it and use nolagg afaik it has a blacklist feature especially for this

if not, check if ther is probably a hopperhog with a mana pool in the vincinity, they have an enormous range when supported with mana

for additional workaround, install item an transfernode with a world interaction upgrade and drop a filter for the desired crystals, it will suck them up when they finish ... don't forget for every upgrade the sucktion range will increase 1= 1x1x1 2 = 3x3x2 ... or was it 3x3x3 ? well, what i mean is, you can place it behind the growth accelerators :P

I think that it might be by design.

Code could have changed since I last looked at it, but previously the seeds
had their despawn time set to a greater time than the time it takes them to
grow (IE they'd never despawn). However, Pure Crystals didn't have that
setting and would in fact despawn after the default time.

That is correct. Full grown seeds are subject to despawn settings unlike seeds still in the growing stage. Slap a transfer node on it or a vacuum node to such up the grown seeds

Growing crystals whoe switched from growing to finished will not despawn. They are still the same entity object, which will constantly reset their life time to prevent them from despawning.

This will only happen, if a player or machine picks them up when fully grown and drops them again. In this case they will be spawned as a normal item entity, which will despawn after 5 minutes.

Or some mod deletes them from the world, nothing we can really prevent.
