Invalid range: [Mon Mar 23 00:00:00 UTC 2020?Wed Feb 26 00:00:00 UTC 2020]

But there is no such taks with this date.

Please help

Can you please share the project file and provide more context?

Hi Dimitry,

I have probably found the problem, there was a parent task with tow sub taks.
It was originally all planned for February, but the due to independenci of the parent task the parent task was moved to march, but the subtask stayed in February, after moving the sub tasks to March as well the error disapeared. But when I have moved one of the sub task to February again, the erro did not apeared again. Shouls not allig the date for teh parent task with the sub tasksPlan White line stage II test&0-series .gan (9.7 KB)

How did you manage to pull “P1 - testing…” out of its summary task range?

HI Dimitry,

I don`t know any more, I noticed it the other day, so don’t know any more what exactly I have done, but it was not done by purpose

regards
