Planed task longer than expected

Hi,

I'm puzzled by a task planned end date when :

• I create an "task" activity, to be planned "as soon as possible without any date set (excepted the "handled date" which is automatically set to today
• I assign some resources to it - say 2 developers, each one is supposed to carry the job in just one day
• I do not fill "validated work" expecting ProjectOR to deduce its value from the previously set resource allocation effort (i.e. 2 days)
• I make ProjectOR compute the planning, set the project start date to the 1rst of November
• The activity stretches from the 1rst to the 26th of november ?! Why 26th ... ? Did the zero value of the validated work misleads the planning computation ?
• back to the activity panel, I set the "validated work" to a value of 2 days
• I try another computation of the planning. The task still lasts nearly a month long...And no way to directly change the planned end date
• the "planning // monthly planning resource/project" report shows some planned activities set randomly between the project start and the mysterious 26th of november (the planned effort is correct : 2 days)
• I failed to find in the forum any similar experience. I was expecting ProjectOR to plan the two developers to work on the task the 2nd of November and complete it within 1 day

Thanks in advance again for any hint

The project I created is quite simple. Resources are not affected to other tasks.
Affectation start date is not filled (I suppose the affectation date is the "start date" associated to a function like "analyst", "developer"... in the resource panel.
There's no dependencies.

Surprisingly the gantt planning is (nearly) correct this morning. Apparently, disconnecting then reconnecting has fixed the issue on every activities but one.

I'm using Project'Or RIA V3.4.4 Quite reliable up to now
There's at least 2 or 3 years of tickets stored inside.
I'm not so keen on trying to upgrade at the risk of losing all this history... or backing up, trying to upgrade then returning to the current version.
Is there a migration path from v3.4.4 to 4.5 ? Is it straightfoward ?

Still many thanks

Shame on me !
I had some old unclosed tasks on a forgotten project I didn't care of.
I fixed their remaining work and the planning is fine now !
ProjeQtor is still the only project management tool I really appreciate !

Upcoming test. Stay tuned...

Just backup our database before (but you do it daily don't you ?)

Our projector instance is hosted by a VM. A snapshot of the VM is regularly backep up
