How to correctly import into Blender

Hi,
I'm able to install and import particles into Blender 2.80. I'm using the .bgeo file format and the following field names: id, position, pscale.

When I import the particles into Blender, they appear correct and I am able to animate through the frames in layout mode.

However, as soon as I change certain settings, e.g. turn off physics for the particle system, the particles blow up and get scattered all around the place. If I do not change anything and just render the sequence of frames straight away, there also appears to be some gravity/physics/collision detection applied and the particles do not end up rendered as initially shown in the layout editor. They fall through the ground plane or sometimes get split and go in different directions.

I realize this might not be an issue with the import script itself, but would someone happen to know what might be causing this?

Blender closes when trying to render a simulation

Unable to render fluid particles. They do not load or the blender closes.
This applies to rendering animations.

Blender 2.81 does not work

Hello.
Today I learned about the existence of this add-on.
I am very glad that you created it.
I tried importing bgeo files into blender 2.80 and everything works.
But blender 2.81 (official release, windows os) does not work.
Prints this error to the console:

[<function load_post at 0x000000000EF6FA68>, <function load_post at 0x0000000010
60F9D8>, <function loadPost at 0x000000001220D168>]
Frame Change 2
TypeError: __call__() takes 2 positional arguments but 3 were given

And I have some questions:

Do you have plans to make blender scene exporter in json format?

Will a polygon fluid surface generator and a foam generator be added to the splishsplash simulator?

When I import bgeo files, blender writes to the console. Particles are not imported:

Traceback (most recent call last):
