[0.18.22] Translations requested on the same tick that a game is saved are not fulfilled when that save is re-loaded

Long-winded title, but this is a long-winded bug. It's actually been pestering me for months and months, but I assumed that it was the fault of my translation handler module. No longer do I think that!

The gist of it is, translations that are requested on the same tick that a game is saved are never returned if you reload that save. To reproduce:

1) Download the attached sample mod, and load it up.
2) Start a new game
3) Dismiss the freeplay explanation bubble, wait half a second (ish)
4) Save and reload the game
5) Wait half a second (ish), then pause and check the game's log file, scrolling to the bit where the save was reloaded

What you will find is this:

Code: Select all

As you can see, on the same tick that the game is paused, ten translations are requested. When the game is saved and reloaded, those translations are never returned.

If you save, and choose not to reload, the translations will be returned like normal.

Thank you!

Thanks for the report. This isn't going to be changed; the same thing can happen in multiplayer if a player gets disconnected before the action gets processed by the server.

The action is always going to be unreliable; but it's the best option that exists.

Thanks for the reply, but I disagree with it being a "minor issue" because there's no clean way to deal with it. In singleplayer we have no way of knowing when a game is saved and reloaded so there's no easy way to tell when this might happen.

I can work around it for now, but I do hope this can be dealt with before 1.0. Perhaps a new event for failed translation requests could be made, including the player_index and the localised string it wanted to translate?

I don't see it as ever changing. The options were: I don't implement the feature at all or I do it like this. I can always remove it if you think it's really that useless as is.

I never said it was useless? I apologize if it came across that way.

If I do ever think of a way to make it work outside of "send request, hope it comes back" I'll implement it, but for now this is the best I was able to come up with.
