-When using half slabs in the mod, such as bamboo, they break in a single punch when they are top half slabs. The bottom slabs and two slabs connected to make one block appear to interact normally and accordingly to the axes/fist used.

-Starfish seem to drown, regardless of being on land or water.

-There seems to be a problem with tropical fish spawning using their egg. They spawn 3 or 4 blocks away from where one used the fish eggs. Another particular glitch is that the tropical fish will only spawn in a single location once you start interacting with them, such as spawning or catching them in a bucket then releasing them. Actually, all aquatic mobs seem to stop spawning with time.

-The blow dart's potion effects appear non-existent. Notably, only the first dart that hits an entity will inflict damage. Subsequent darts shot at the same entity seem to miss or bounce off entirely.

-I've yet to see a sea star, man-o-war, urchin, or turtle spawn naturally.

-Planting Iris' causes their heads to pop off.

-Sugar cane appears to grow at a painfully slow rate using this mod. Unsure if this is a result of Spigot (MCPC+) or it's the actual mod.

-Are Eudialyte and Zircon tools suppose to be less efficient than stone or iron tools?

-Spamming a stack of buckets on the tropical water results in the creation of regular water found in the overworld.

-(Suggestion) Bamboo spears are as powerful as iron swords. That seems slightly broken. Any chance of lowering the damage output? And Daggers are only as good as your fist.

As a side note, congratulations on fixing the Koa villagers. Very lovely update.

These seem to be fixed in the upcoming 1.10.2 release. Feel free to create separate issues for each of these you find that are still bugs.
