Whenever I export an animation from blender, the transformations are incorrect and produce weird results. For example I made an animation in blender to be exported to roblox 
but in roblox the arms and legs are messed up whenever the animation plays
which is clearly nonexistant in blender. It’s happened with every rig i’ve used so far including the default roblox rigs

There’s currently a bug where if the rotation matrix of Part0 does not equal that of C0, the rotation transforms mess up. It’s still a bug I want to fix “at some point”. Most rigs don’t really have this issue though (R6 does, but R15 isn’t).
I think that’s also the issue you’re experiencing.

When I export the rig it adds a load of parts to the rig which then import into blender and I get an error:
I made sure that the .obj import addon was enabled.
Are your Motors all parented to their Part1?

Can you send both the place file you used + the obj you exported from it?
What @ScriptOn said is also true, the plugin only seeks for motors in either their Part1 or Part0 (but probably does not cause that issue).
Btw I’d like to thank you for the importer. I was able to use the base importer to help me convert roblox animations (and thus, mocap/blender animations) into my animation editor:

Thanks! It’s really cool to see it being used in practice

When I export an animation, load it into the plugin, and export, poses are being created in every keyframe for bones that were not modified throughout the entire animation, thus freezing them.
I don’t remember this happening just yesterday, did I do something to cause that or is this intentional and I just missed it?
That’s normal, I haven’t added a way to disable certain bones yet (like those checkboxes next to the bones in the Roblox animation editor).
You can open the animation (or generated KeyframeSequence) in the Roblox animation editor and disable bones you don’t want, though. Or if it’s useful to add it to the plugin itself I can probably do that too short-term.

Same here.
FYI: From the Mixamo site…
On August 22, 2017, the following assets and services will be removed from the Mixamo site.
- The ability to save and retrieve assets in “My Assets”.
- The Face Plus facial animation plugin
- The Decimator polygon reduction tool
- The ability to download Control-rig scripts
- Download types for .bvh and .biped that streamline integration with 3rd party applications
- Mixamo forums will close and all help articles will be moved to Adobe’s HelpX

Are you guys using pre-made animations in mocap or making your own mocap animations?
If you’re using mocap, what product? If not, where’d you find the animations?
someone download all of these and upload on mega, pls

This is the internet, it would be weird if someone hasn’t already done that (not necessarily someone from Roblox)

One thing that I hope you guys add (or is already there) is the ability to work with multiple ROBLOX rigs at once. I want to be able to animate things like 2 guys fighting, or something like that. Any way to work with those multiple rigs?

You could import + generate one rig, rename the __Rig and __RigMeta objects to something else (postfix a 2 or so), then import another rig. The plugin always looks for those objects by name when importing/generating/exporting, but you can animate both rigs simultaneously in Blender just fine with different names. Just rename it back when exporting.
