eloquera database plugin - some classes wont work

i work for the database plugin again. and i need to say, as far as i am it looks pretty cool. but i still have on problem i can't solve myself.

i did some network extension, so multiuser can access a database hosted on a server.

till now i did extensive testing and i found this:

there are some objects i can save like :vectors, points, strings,
float and integer and there are lots i can't like: planes, breps
(surfaces), lines, circles, ... the items i save can be accessed by many
users and are persistent. but the ones i cannot save correctly, i
can just use in the single instance of the program with my .dll i created
them and stored them in the database - as long as i don't close the program.
it's like there is some sort of connected to something going on in the
memory. some of the unsaveable items create an error message when i
try to access them from a second account like : nullplane, line (0.00mm)
or invalid circle, while others just crash rhino (some sort of
display error).

i know grasshopper has classes for every geometry (like point, plane, line, vector and so on), but for simplification i saved e.g. a List as a List
