Crash report

Description / steps to reproduce

The game crashes after having a big portal teleporting mobs for a while. This is a portal spanning over two slime chunks in skyblock at Y=-64, so it's big and teleports a ton of mobs.
The crash happens a lot sooner when putting a second portal over another two slime chunks.

Edit: Also happens with small portals. All that matters is that you send a lot of mobs through it.

The bug can be temporarily fixed by putting a block of wool under the block (the bug is coming from the sound and the sound code doesn't run if the blocks is silenced)

My bad I read the wrong code
We can only silence the pedestal

Additional information: The bug is reproducible just with Draconic Evolution v3.1.2.583 (and it's dependences)
So it's not a compatibility problem.

Being able to silence the portal would be a nice feature though. Having a lot of teleports can be pretty loud and annoying.
