It's a known fact that some track files will not play back properly. This has been a problem since at least 2014, and continues into version 1.5 Openbeta 1.5.5.58642.188.
The symptom is that after a certain point, the player pilot will no longer be receiving input commands. ie: it will continue its trajectory until crash after a certain specific point, but it appears random to the user. Suggestions include the time zoom function, but that only matters at extreme acceleration levels. The right suggestion is that it has to do with TrackIR (or event count), but nothing ever came of it.
A .trk file is zip file that contains the mission, input data, random seed, options, and other stuff.
I looked at track files that I could not play back properly, and the size ranged from 51884KB to 67005KB so it doesn't seem certain types of errors are at cause. I'm guessing that the entries in the track database are variable length, and it's a total entry count that's causing the problem. This could be a programming limitation or LUA limitation. I don't know, but I'm requesting this long-standing bug be brought up to the front again. I'm willing to test it.
