This server is really fun. The implementation of Slimefun is a great addition to the game, however, it does have a pretty big flaw. All of the custom trees have 6-sided logs (bark). This makes it so that it is much harder to find regular logs. In addition to this flaw, the player is unallowed to grow trees from saplings. Whether this is a bug, can be worked around, or is intended, I believe that the player should be able to grow trees from saplings so that they don't have to buy or painstakingly search for the regular logs.
