Anyone else found that pre-release 1.4.3 breaks breakpoint debugging?

I have one project which uses the latest pre-release, and I find the breakpoint debugger acts crazy in that project.

Many breakpoints are skipped, some have hollow circles in the middle, and when I do stop on a breakpoint, stepping over becomes like "wormhole travel" through my code, it just randomly jumps about everywhere all over the source files, irrespective of what lines of code the actual runtime is executing.

Does it in android and iOS projects.

I get this output too in the logs too:

Mono.Debugger.Soft.CommandException: Debuggee returned error code 200.
