A: oh hey my commit is not in the master branch...
A: *seeing bunch of commit deleted activity in bitbucket by B
A: Lol B deleted commits in master branch
B: Wait, what?! I know I have rebased my branch.. but never have I rebased anything in the master branch.. how can this be *intense breathing
B: Are you sure you have pushed yours to master?
A: Sure I've rebased, squashed, and rbt landed my work to master, here look my local master has my commit
CTO: wait what? Is this related to this bug we have in production just now? Please don't panic, let us resolve it

Turns out rbt land just squash your commit to your local master branch and they thus A have not pushed it to the remote. And the bunch of commit deleted activity were bitbucket not informing from which branch the activity was happening. Almost gave us heart attack.
