A: In very rare cases this can happen. It's only the cached previews that are wrong in those cases, not the images themselves.
This is very easy to fix: just hit "Shift-F5" to recreate the previews.
Explanation why this might happen: when first loading the sequence, LRTimelapse uses ExifTool in Background to extract the previews. This will normally only happen once, and then the previews get cached by LRTimelapse. If you interrupt this creation process, LRTimelapse tries to kill the exiftool process to be able to load another sequence. But sometimes this does not work instantly and then ExifTool still delivers a preview from the previous sequence then when you already are loading the next one.
How to avoid this completely: Wait until the previews have been generated completely when loading a sequence for the first time.
Another way to avoid this is by using the LRTimelapse importer - it will generate the previews right away when importing from the card, so you will never have to wait for the preview generation process anymore and never get scrambled previews.
