Before the 3rd of May 2016 there was a chance to receive 2 protean planks instead of the plank you are meant to receive when converting certain logs:
4% chance when using logs
6% chance when using oak logs
8% chance when using teak logs
10% chance when using mahogany logs
There was an increased chance of receiving these during a promotion from 2/05/2014 until 6/05/2014.
