hey one minute my dinos were in my inventory...next they weren't!!!!! ive lost a fair c h unk of my tamed dinos, they're not in the soul trapper...

Generally speaking, if you lose a lot of inventory items there's 3 possible causes in order of likely possibility:

1) Your toon or storage item is slot capped / beyond slot capped.
2) Your lost items are modded items, and the mod either updated, was disabled, or impeded by a third party. (Mods made by Ertosi have this happen to their newest targets once an update.)
3) Your character profile is corrupted.

To fix #1:
Take your character to a storage container, and deposit all of the other items on your character, and see if that frees up the inventory.

To fix #2:
Perform a rebuild on your server, once the rebuild completes, roll back your server to an earlier save file. If it's not fixed, then you may need to seek assistance from the modder's community for the missing modded items.

To fix #3:
Roll back your server to a period before the items dissapeared, (such a rollback should restore a prior profile save.)
If a roll back doesn't restore it, then you may have a permanently corrupted profile. If that's the case, then there's very little that can be done.
