With the info given, it's entirely possible that the bug was actually in version A. Perhaps sending it a payload that is perfectly acceptable by the spec of how the API should work caused A to crash.
In that world, "fixing" B could involve sending invalid or unintended data to work around the problem in A, or patching A before rolling out B (which, when you're at the point of rolling out A.2, you may as well just roll out B)
