Well, I know for a fact that people with faster computers are literally in the sim and playing before other people have caught up. I've observed that with DRB, with two machines in the same room.How can that possibly desync you? Can you give more details?
If they're delayed enough, I think that causes a sync error due to timeout. Best guess atm, I haven't the foggiest how all of that works.
The full installer's basically a complete install of Spring. I wouldn't be telling people to install it, if the "bare bones" was syncing with the full installs, but they don't sync- see my post in Dev about that set of issues.Also KingRaptor reported that uninstalling pure broke his spring install.
If he installed it to the same directory... yeah, it'll do that. There are other issues there- UnitSync / SpringSettings seems to assume that Spring's only installed in one place.
