"There is no bookmark"

[DoctorDinosaur]

Description of bug / unexpected behavior

I keep getting Exception: There is no <bookmark mark='BookmarkName' /> with no obvious connection between when it happens.

Expected behavior

Bookmarks are properly picked up

How to reproduce the issue

I don't know why it happens sometimes but not other times.

Code for reproducing the problem

```py self.set_speech_service(GTTSService(lang="en", tld="com", transcription_model='base', global_speed=1.2)) with self.voiceover(text="""With this result, we can now go back and derive our formula for updating the kernel weights.""") as tracker: self.wait_until_bookmark("A") self.play(Indicate(s1_text), Unwrite(s2_text), Unwrite(s3_text), Unwrite(s4_text)) self.wait_until_bookmark("B") self.play(Write(new_weights), s1_text.animate.to_edge(UP).to_edge(RIGHT)), s1_text.animate.scale(0.5) self.wait_for_voiceover() ``` doesn't work but ```py self.set_speech_service(GTTSService(lang="en", tld="com", transcription_model='base', global_speed=1.2)) with self.voiceover(text="""The kernel weights are updated, or trained, using the following formula, where alpha is the learning rate hyperparameter and W is the kernel weight matrix.""") as tracker: self.play(Write(new_weights), run_time=tracker.time_until_bookmark("A")) self.wait_until_bookmark("B") self.play(Indicate(new_weights[0][7])) self.wait_until_bookmark("C") self.play(Indicate(new_weights[0][0:3]), Indicate(new_weights[0][4:6])) ``` Does

Additional comments

[DoctorDinosaur]

Deleting the media folder fixed it this time, but I shouldn't really have to do that, no?

I think the issue boils down to it not updating if you add a bookmark, only if you change the spoken text?
