I've had this issues where AoE2 saved games (ones I've been able to watch in their entirety in the past) are ending prematurely (anywhere from a few minutes to a half hours) into gameplay. The screen will show as "Paused," and then I am unable to continue the replay. Has anyone else had this problem? Is this an issue with corrupted save files?

hi
not as far as i know.
i assume you using the same patch and mods to watch these games as they were played under

Yes, I am using the same patch and mods, no changes besides usual voobly client updates.

Hi.

Game pauses are usually caused by a mismatch in patch, mod or a combination of both while viewing the recording.

Sometimes if the patch/ mod has undergone recent updates/ changes you may experience the same issue but in those cases there is not much to be done about it unless you can get hold of the exact same patch + mod combo that was used while playing the game.

Please double-check carefully and test again.
