Problem UMMU 2.5 Possible Bug

[romanasul]

Hello, I seem to be having a weird problem with my UMMU's. I'm not sure if anyone else is experiencing this so here I go. Whenever I change the MJD date past a certain point in the scenario file or while the game is running the RCS thrusters on the UMMU's fire whether the suit is on or off. This happens on the moon and earth and the UMMU's topple over when trying to move and they jump up and down. There is also a thruster animation seen on the UMMU even when the suit is off. Any help you guys offer would be greatly appreciated.

I have exactly the same problem. It even happens if you create new UMMU using the scenario editor.

I guess they just have an expiration date.

Edit: for some reason they start to have problems gradually. They start to jump in about the year 2500. By 10000 they are completely useless.

Yes,I too have experienced the same problem with Ummu2.5.

This is a long known issue, and I believe it is documented.

IIRC, it has something to do with the year 2000 being the reference for calculating planetary orbits. The uncertainty in the position of a planet itself for much later dates makes the UMMU slip and slide. There is no way to fix this.

For best results, conduct all UMMU operations in the early 2000s.
