Hi @TehGimp666 I just tried 0.1.2 with my friend to complete a space docking. We two launch a space shuttle and a spacecraft into the low orbit. Then we can quickly see each other and the sync is good enough once the distance is more than 50km. Then, we did the intercept, and we can observe that one is approaching another. Before getting too close, the sync worked well and the accuracy was good. Then when we got very close, e.g. 3km. In this case, we can see each other and the craft can be well rendered. However, after getting too close, the server sync did not update frequently enough, so sometimes he saw a 1km distance and 30m/s relative speed, while I observed a 500m distance and 15m/s. After doing warp, and then sync, this can be temporarily solved. But after a while, the error became large. So, we decided that one did not do any operation and the other completed the left docking. So finally, the two got close and then combined together. Just after docking, I lost the control of my vessel, and returned to the tracking center. Then I asked my friend returned to tracking center, and I took the control of the combination. I separated them, and took the control of my part. However, after that, my friend lost all the info of all vessels. Even reconnect to the server, there was no vessel can be observed by him. But if I did not disconnect, I can always observe two from tracking center. If I disconnect, and then reconnect, I lost both as well. After all, Id like to say, 0.1.2 gave us reaaaally fantastic experience. If the sync can be improved for closed craft, and the data can be stable (sometimes his was in relative higher orbit, then after a while, sync, we found mine was higher), the experience would be much better. Thanks.
