You'll probably see the reports of it on Steam (and maybe you've already gotten some from Discord), but just in case i'll make one here :
The fix to
this bug backfired.
Some have reported not getting those achievements, and have scoresheets proving that they did in fact hack enough machines.
Looking through scoresheets in the run history and through Steam achievements, i haven't found a single person who actually got either of those achievements during Beta 13.
For example, one of those who reported the bug on Steam has a scoresheet where they accessed 59 machines, and hacked at least 10 Main.C machines, but they still don't have the achievement :
