Sometimes in job systems from Fearsome Aspect and onward, i get either the ‘Solution is invalid’ error or the ‘Tried to activate a hidden port before revealing it!’ error.
I can’t even start to solve the two new jobs.
I’m sorry that we haven’t replied sooner! We’ll be looking into this within the next day or so and should have a solution shortly thereafter.
We’ve got a solution in testing. It turns out that there was a rather major issue with how semaphore nodes behave in the server-side solution simulator. We’ll need to be careful when testing the fix to make sure we don’t make anything worse, but we hope to have the fix deployed soon.
We deployed a fix tonight that takes care of the issue: Update to 0.20.0
