Another _bug_:
Level 1:
Fragrant Pipe Cactus
Lilia Orchid
produces Mela Fanleaf which is correct
Level 2 shows
Mela Fanleaf + Fragrant Pipe Cactus = Aureus Bamboo which is incorrect. Fanleaf + Pipe Cactus = Maple, not Bamboo
Note if I put the fanleaf and pipe cactus on Level 1, it calculates level 2 correctly (maple), so it appears there's a problem with level 3 calculations.
