Not a problem. Way I see it, if you don't see any differences in game play, your console isn't getting spammed, you are able to start the pack, and there isn't giant lag spikes/drops, you have nothing to worry about.
I'll try to get you some of that information. It "looks like" it could be a java issue according to the guys on CreeperHost.
I also noticed that at the very time I was trying to run it, they were in the process of releasing an update. hahaha
I'm having this same problem but its affecting game play. It stuck an obsidian tile in my hot bar. Now when I use my ardite hammer it places down the block beside it on my hotbar
