Whilst travelling through hyperspace, my HP suddenly decreased from 90 something to 41 for no apparent reason. My character was at level 4. I'm now, inexplicably, at level 3 with a maximum HP of 41 - it was up in the 90s before! I also now seem to be level 3 and I have hundreds of action messages saying "you reached level 4" and "your HP are increased to 41". I have been in no combat of any kind - all I was doing was flying from Kho Nai to Sullust. What is going on?
