Compact chest from the compact storage mod are resized down to 27 slot (from up to 288 slots) and all contents are deleted with the comment "you tried to do something bad :(".

This is really bad as I moved a 288 slot chest that was full of all my botania items and I lost everything, with no backup as the server admins were not around and the game wrote over the backup.

This is modded minecraft, there WILL be chests of varying sizes, and I have never heard of ANY client side exploit that would allow you to resize chests server side. Please remove this check, as there is no reason for it, and it will cause massive issues with many mods that resize chests unless you put in checks for those specific mods, and any new mod that pops up will be vulnerable to this issue until it is brought to your attention and you add a check for that mod.

Please leave it up to server owners to blacklist the items they believe are in danger of exploitation.

I hope you realize that the text "you tried to do something bad :(" does not show up anywhere in Sanguimancy.

Can you help figure out where it is coming from? The dollies don't do it, thaumcraft doesn't do it when moving them, no other mods that move blocks do it, but it happens with the transposition sigil and only the transposition sigil, that is why I came here.
