Follow this events order as example:

OnEntityCreated -> PostSpawn -> RequestFrame -> CreateTimer(timerReadEnt) -> EntityDestroyed > timerReadEnt

in timerReadEnt you will get an exception if you use the entity index cause it's gone (or replaced by another entity with the same index).

Storing the entity as EntRef allow you to post-check if that entityRef has an INVALID_REFERENCE (with EntRefToEntIndex) before using it.

The logic is the same as what happens to the player. (GetClientUserId)
