Spawn Icons Recreating

Hello, I have a little bug that is a bit annoying:

Each time I restart Garry’s Mod and I go in a spawn list, all the spawn icons recreate! It’s very annoying since it makes lag.

Any idea?

wow, that must be a pain in the ass

Does the same for me. It never used to…

By the way it’s annoying the most with the SProps addon since it has huge amount of props.
