How can you watch old Replays?

Is it possible to watch Replays which used older Zero-k engine versions?
If i try to watch one it does display 0% "Numbers of Zero-k version" like it is downloading something,
but doesn´t download anything in the end.
I wanted to watch a Replay which was ~4 years old, which did not work
and then tested to watch some 2 months old replays without being able to download/watch them.

Thanks for your replies.

Wait a while, the engine is downloading. That is, unless we deleted the old engine version. Spring infra may also delete old test ZK versions. You should provide more details.

I just tested and ran a replay with a different engine.

Huh, hadn't noticed that.
I try and replay this: https://zero-k.info/Battles/Detail/586451
and I get an "Unable to download replay file" message.

Test with 4 years old replay:
B225680 2 on Geyser_Plains_TNM04-V3

Game version: Zero-K v1.2.1.0
Engine version: 91.0

after 30 min of waiting the loading is still stuck with the following information:

Waiting on content:
-Zero-K v1.2.1.0: 0%
-Geyser_Plains_TNM04-V3: 87%



Test with 3 months old replay:
B600313 8 on TitanDuel 2.2

Game version: Zero-K 1.6.7.3
Engine version: 104.0.1-287-gf7b0fcc

No Box in the center but popup instead with following information:

Getting data...
Downloading replay file.
Unable to download replay file

Replays which are about 2 months old still work but everything else wont.



Edit: 2 months old replay
B604954 6 on Mini_SuperSpeedMetal_Wide

Game version: Zero-K 1.6.7.3
Engine version: 104.0.1-287-gf7b0fcc

Able to download and watch.

Somehow a game which is only 2 months old can be downloaded and watched, but not a 3 months old replay.
Even tho they have same Game/Engine version.

personally I think there is so many trash games every day vs ai and stuff, 1 hour long big file size chickens games etc

there should be a prioritization, tournament games shouldnt be deleted and 1v1s should get priority over team games

Deinfreund speaks words of wisdom,we must simply post on the replays we wish to save for future enjoyment.

But even commented gamesm from years ago dont work,so i think its just chobby.
