Two bugs, the first being that once you add water, garden lime and a pelt into a barrel, close the lid and toggle for 'Tan Leather' you may receive the prompt "I need to add pelt to tan" tried moving items around, adding more water, re-logging into the server and tried other servers with different lime,barrels,water and other pelts. let me know if I'm missing something!
The second bug is related to the first in that sometimes picking up a bundle of leather will make your character stretch like liquid metal from Terminator 2.
