🐛 Describe the bug
I have been facing an issue with a voicebank I had been debugging. I wanted to regenerate the LLSM files for the voicebank due to some audio issues, but for whatever reason, the voicebank just stopped producing audio, despite being properly OTOed. Opening the voicebank's files revealed that it wasn't regenerating its LLSM files for whatever reason, even though Moresampler is supposed to regenerate LLSM files if it detects none are present. Installing a newer build of Moresampler, clearing the cache, or even killing Moresampler's processes in Task Manager had no effect.
For some reason, Moresampler only manages to partially regenerate new LLSM files for the voicebank shown (Macne Nana 2S's UTAU port by Cabaret Do Ike). Some audio still kind of works, but others don't. Copying LLSM data from an earlier version of the voicebank did not help and produced no sound, either.
Is there any way to get Moresampler to properly regenerate new LLSM files? Perhaps there could be a way to manually instruct Moresampler to generate LLSM data for a voicebank in its command prompt?
Explains how to reproduce the bug
I do not know the cause. That said, it does not seem to affect all voicebanks, just my copy of Macne Nana 2S by Cabaret Do Ike. However, it can be noted that no LLSM files were in the voicebank's database at the time, and "auto-update-llsm-mrq" was set to "on".

Note the lack of Moresampler mentions in the logs. Normally, Moresampler is supposed to show its current process in the logs and debug window, but it failed to generate new audio due to the lack of LLSM files.
