Where were the logs before you took them into inventory?
-Logs came from large crate inside a crate rack.
How many were in inventory?
-5 logs
Did you use the crafting window or right click log group?
-Crafting window was used.
Did you do one at a time or a number equal to your queue?
-used full queue of 4
Did you have in inventory more than your queue?
1 extra log more then queue
something that i have notice was that it always happend with the last 4kg of the log.
