Help Fluid is gone in all scenes

[veelox]

I've been making many changes to my project for a couple of weeks... not all of them have been committed to git or documented. Unfortunately, I just noticed a severe issue with Obi Fluid in my project. Fluid will not render in any scenes in my project, not even in Obi's own sample scenes. The only thing I've seen that can kind of get the fluid to show up is by checking Render in an Obi Particle Renderer in one of my scenes. But even that made it so that the fluid only shows up in the sky, which makes no sense to me. Moreover, I cannot see the fluid in the Scene tab; only in the Game tab.

I am very confused by all this... I must have altered some kind of setting which affects how fluids are emitted or rendered or something. Where can I look to determine the root cause of this issue?
