Update: from discord, all nightly snapshots include this bug. |
|
Can we have a save that includes the bug, for ease of troubleshooting. |
|
Ah ha, yeah, is what I expected to see: Basically the save is failing to complete. So you end up with a malformed save file. |
|
I'm getting spammed with this in my logs constantly when it tries to save I'm running a nonstandard build and haven't replicated on a stanard build yet so I hadn't made an issue, but the XML ends with enum-map and that's what my exceptions are complaining about... |
|
I get the following when saving in 0.50.0 ERROR [megamek.server.GameManagerSaveHelper] {Connection 0}
megamek.server.GameManagerSaveHelper.saveGame(GameManagerSaveHelper.java:80) - Unable to save file: savegames/autosave.sav

Severity: Critical

I cannot reproduce the enum map problem on my .50 install. Saved a game with some mek that had system manufacturers. No problem. |
What do you mean "Saved a game with some mek that had system manufacturers"? Once saved, was the saved game then loaded with the same client? |
|
Yes I saved and loaded. I was talking about the savegame being cut short at a systemmanufacturers entry that uses an enum map and the xstream errors are for an enum map. But I don't know how to make that error show up. |
