Skipping Rests When Exporting to Audio File

[videogame_munkey]

I'm trying to export a drum track to a .wav file, but every time there's a long enough rest, it skips the silence completely, although during the recording process, it looks like it goes through the track normally. It also seems to skip at more random times that I don't quite understand, where it would be much more difficult and tedious to just slice and add a pause in an audio editing software. I have not had this problem until very recently. No such problem when exporting all the instruments at once, only when one at a time. The same issue occurs while exporting to mp3. If this is some result of how the exporting process works, it's a fairly catastrophic oversight, as obviously silence is an important part of music.

Edit: Also it's not only the 2013 drums instrument that has this problem, it's other instruments too.

I am not sure. I think that it doesn't register sound so it skips. Ex: Long note that the sound lasts for 3 measures but gets cut off at 1 measure. Maybe don't make long periods of rest. I use mp3 so I can't completely confirm this.

The periods of rest aren't that long, and it also skips in some less obvious spots that don't have a significant rest at all.

Here is an example, this is what I'm trying to export from:

The wav and mp3 exports skip at measure 19, which makes sense with the idea that it skips long silences, but I think it just skips whenever there is no note at the very beginning of one of the 4 quadrants within a measure. Take a look at the drum pattern that starts at measure 75. In the export, it skips directly to the two notes in the middle of the 4th quadrant, which do not fall on the first division of the quadrant. However, comparing measure 99 to the export, it seems to not skip every empty beat, but only one of them, as the next notes fall about a beat too early. So, it doesn't skip the full rest.

It also skips the last beat of measure 24, but not the first beat of it, but there does seem to be a slightly faster gap. Maybe it's skipping as soon as the cymbal sound has fully decayed? Anyways, this is an extremely restrictive issue, that basically renders the export feature unusable for me.

Ok, so this problem doesn't occur at all on Google Chrome, I recently switched to Firefox while being unaware of how Online Sequencer doesn't work the same on FIrefox, which is why the problem only started recently. I can just use Google Chrome for Online Sequencer, so this is not really a problem.
