I have an issue with MS Project 2016.
I have a task which starts on May 9th and is estimated to 72 hrs. I have assigned a resource, which is available 4 hours per day (I assigned the resource using his own calendar where his availability is set). The task type is Fixed work and it's effort driven. The duration is 18 days, and there are just just 3 working days marked as non-working.
And yet, MS Project calculates the finish date to be July 7th (40 working days after May 9th).
I'd appreciate any suggestions as to what may be wrong.
