Here we are, a brand new items table consisting of the newest 13th floor dump as of this morning (62,000+ items) Stackable items work, and I made the appropriate changes to the columns so all the data got converted and merged in. I've been testing it all morning and had no issues (other than pre-existing ones in the Emu code of course) so it looks like we are good.

As Wild said, Linux users will probably need to bump your /proc/sys/kernel/shmmax file a bit. Windows users need not do anything.
