As of Beta 0.6.1, running on minecraft forge 1.8.9-11.15.1.1722, several blocks in botania display a pink and black texture rather than what they should look like. In order of severity:

• Lexica Botania's first person render when held in hand (barely noticeable, only affects 3d render).
• All four varieties of mana spreader's inventory renders are untextured - however, mana spreaders render with the correct texture in world.
• The mana pump, both in world and as shown in inventory.
• The Plains, Mountain, Swamp, and Tiaga petal apothecaries, again both in world and in inventory.

I'm very aware of all of these :P

Are most if not all the texture/models errors fixed? I was waiting for most issues to be fixed before adding this to our server. I am by no means being impatient, it is a wonderful thing you have done, taking on this port. Thanks!

Yeah, only the spreaders' item forms and the lexicon first person model are out still.
Spreaders will probably be done within the next few builds, lexicon a bit longer (still got some stuff to figure out)
