error reading mission state file

[Vacuum-Tube]

Hi, your mod creates an issue that there is a -nan(ind) value (e.g. 0/0) in the state data. This leads to the fact that a savegame is no longer loadable. ("error reading mission state file")

Thanks, I'll take a look shortly.

Thanks for linking the forum, it's obvious where the error is in the state file ("usage = - nan(ind)"). However, I'm unable to locate any obvious reason why this would happen, and have not experienced it myself in any of my own testing/long/big save games.

Your suggested solution in the forum thread is the way to go for now - there is no important state data saved (at this time), just delete the lua file or the erroneous entry. Confusing, this should not really be possible - I've clearly missed some odd edge case that can occur.

[120223] = { capacity = 85, demand = 34, mode = "(D)", name = "Belsize Bus 3", occupancy = 15, rate = 44, samples = 1027, usage = -nan(ind), vehicles = 5, },

Separate note; I'm unable to register on the forum (registration not enabled at this time due to bots?) - please advise the original poster to look here, or simply to confirm that your proposed solution is the way to go (for now).

Also, thank you for submitting the issue! I'll keep it open for now to see if anyone else shows up with the same.

Registering should be possible.

Thanks, you're right! I'll correct this, and probably expand a bit at the same time.

I've also registered now, I mistakenly got the impression that registering had been disabled due to the abuse.

I'll keep this issue open until resolved proper.

Pushed a quick fix for the possibility of the error occurring again a6115409f7784e209868c5cfeed11d393728e599. This will however not fix already occurred errors.

[TommyC81]

Actually, also changed version of saved state. That skuld invalidate previous saves and resolve the observed issue.

[TommyC81]

I gather this should be resolved now. Will close the ticket.
