Bit of an odd one... just run an MP session with this sim chained to W Yorks and to Doncaster North (both acting as the server end of the chain, with DN subsequently a client of WY).

We ran from 0745 to 1130 sim. My global setting is to auto-save every 60 minutes, which WY and DN did on the hour. But the Ardsley sim only saved once at 1100 - not 1000, 0900 or 0800! (The saves did not already exist to need overwriting)

I suspect this might be Mantis 31477 (which had been deemed as not fixable back in 2020). The underlying issue I had come across was that if any secondary chained sims are a bit slow with reference to the master sim at the moment a snapshot is due, the cross-chain time syncing can then cause the clock on the secondary sim(s) to jump forward from e.g. 16:59:59 to 17:00:03 or something like that - since for that sim therefore 17:00:00 never actually happens, the corresponding snapshot is omitted.

The recommended workaround was to set the save interval to something more frequent.

Two million people attempt to use Birmingham's magnificent rail network every year, with just over a million of them managing to get further than Smethwick.
