For next patch the performance for building extremely large Vaults and Lairs will be way better, because parsing them can be avoided thanks to having only one (invisible) prop on each tile and nothing else.
We check for this case now and do no parsing work at all.
The performance for building other types of rooms will not be improved by this change.

We do now inject this translation key for the neutral faction when ever a skirmish, sandbox or map editor created map is loaded.
Thanks for finding out about this issue, it should be fixed in next patch.

I totally misunderstood and thought you encountered the issue in My Pet Dungeon mode.
We found now that Skirmish  & Sandbox maps do not have the translation key set, because these maps are made differently than official campaign maps.

We will look into that now and try to find a fix.

I thought the translation IS NOT present in My Pet Dungeon mode (as well as in all other modes)?
However there shouldn't be differences between the game modes, if any then it could be specific maps which have no translation key set on the neutral faction.
Is it the same for all maps or not?

I wonder if we did any internal change on this matter since the last public patch was released,
but I am not aware about any.
But as you can see in the screenshot above, in our internal version the translation is applied correctly and so any community translation should be applied correctly as well.
I will have to double check this with collegues tomorrow, but no matter what, it seems to be fixed and working correctly in our internal version, so it should be fixed with next patch release if it doesn't work yet.

In case you still get no translation after switching fully to official translation only, it could mean that the problem is with your GameText.csv file.
Maybe it got not correctly updated with a patch or somehow corrupted.
In this case I recommend to Verify Game Cache.

Btw. the behaviour should be the same for any game mode.

What can I say, I just tested it as shown in the picture above and it got translated correctly.

You know that it is not enough to select the official unsupported translation, but you also need to deselect the community translation (select "None" as community translation)?
Otherwise the community translation will always have priority over the games original translation.
So if a translation key exists in the community translation, the game will never bother to retrieve the original.

If you have community translation unselected and official (unsupported) translation selected, is it still not translated for you?

In case it is, it means simply that the community translation contains the English word where it should have the Russian one.

@Cian please have a look at UserEcho, looks like there is a faulty community translation used which does not translate the key for "Neutral".
