Blocks created with more than one texture causing freeze/crash at times when multiplayer server load is high and TPS is below 11 -- it also happens when ping is low for any one player on the network.

The best I can explain is that when breaking some blocks, the block turns into its default (clay shingles, for example) and then when a break of this block is attempted by any direct means (you can clear it using ultimine or cardboard boxes, for example) the client (and sometimes the server) will immediately freeze and/or crash. Usually the client freezes and this is on multiplayer so I don't have much in the way of logs.

This is for version 1.19 1.0.111-BETA on Forge 43.2.14. I'm posting here because I've had this happen in a few packs so far. The most recent being ATMVB.
