@trink I was wondering how you're catching all of these, are they coming up from daily use or do you have a fuzzer set up? Thank you for all the fixes so far, especially since they come with test coverage! |

@archseer I created a fuzzer because some came up in daily use :) I was thinking about generalizing/cleaning it up for release. If you are interested let me know. It is scriptable and has the ability to stop before the failure, on playback, so you can set some breakpoints and interact with the editor etc. It also tracks all command timings to discover things like #5851. |

That sounds very cool! I would definitely be interested in giving it a look and I'm sure @archseer would too |
