Getting a number of these errors on my build for sandbox and download

I Have a number of projects that error out with
Resource not found
Model Item : task
Id : 2

2.5 builds
Just changed the names of these projects - to obsecure their names from public view
Projects
Fatal - Birthdays
Fatal - Shop
There are a few more

but i need time to list for you perhaps tomorrow? (its like 3am here)

Many Thanks in advance

I am guessing it has something to do with the question marks on the save and new buttons?

Fatal-Shop
-Removed the save and new and save to copy with question marks from the toolbars
- rebuilt
- no change

noticed some item toolbars had delete function (new toolbar in 2.5 does not have delete button)
- removed all delete buttons
- rebuilt
- no change

Removed and rebuilt all toolbars in front-end item layouts
- rebuilt
- no change

Removed - Delete Button From Backend Item toolbar
-rebuilt
no change

Removed and rebuilt backend item toolbar
- rebuilt no change

Tried various config settings - no change

tried 3.0 build - no change

tried 2.5 build again - no change

I give up

Ok Have been in and opened ALL of my projects (yes there is heaps )

- Tried to download each and every one

Have renamed all projects that failed to build for download
- project title only has been changed
(Again project title has been changed to mask some projects that cant be named publicly)
- project title starts with Fatal - XXXX
- project alias left as it was so i can rename again later

All except one Fatal - xxxx projects give the - Resource not found Model Item : task Id : 2

Thanks in Advance

Fixed.

Please try again.

The fatal is fixed, but still there is an incoherency and it can raise other issues.
But do not worry I am here and will fix what is coming.

Please retry all your projects with this issue.

I have a big problem because my IDE is down. Aptana has a big problem and I cannot use it anymore.
Dreamweaver also the same day (sunday)

So I am currently fixing with text editor.
I am a little bit stuck with Aptana, wich is good when it works, but actually... big problems unsolvable.
I understand for you the same using Cook.

NO WORRIES!
I dont worry when its in your hands - I know it will be fixed in good time
No Rush!
I understand your pain... Will Try to rebuild

Rebuilt all Fatal Error Projects with this error and they now pass - Thanks
(i understand that they pass with "hidden" errors)

but still there is an incoherency and it can raise other issues

I know you said dont worry....... but while your having issues with your IDE
As it seems like it is confined to my projects
To help out could I rebuild the areas of concern?
would that help?

- I noticed most if not all of these projects used Juser
- Is there some old field types that i need to fix?

It can happen when you have a column in the grid referring to a linked task, or linked layout (in properties, not direct task in grid)
When you delete the refered task, or layout, then the system will ignore, which is normal at the end, even if the key is still present.
In 'groups' (grid, combos, filters, ajax), it is the same, when you have deleted the original table, of field, then it passes but the result is weired. Better to replace the good field, and reset the groups.
Can be improved.

Thank You Admin for taking the time to explain it is most appreciated
and it is always good to have some background information so that we can prevent the issue in the future
