Bass gone rogue

I have a score by another composer to submit, I’ve made few changes, layout is not great which is fine, but I lost the bass1 from bars 44-67. Anyone with few ideas, I’m attaching the score, thanks

This might not solve the problem completely, but unhide signposts and then delete the " -1 staff " signpost at bar 30 (in the Bass layout).

Thanks, it seems to work!
