After upgrading a 3.0.4 system to 3.1.0 some strange errors occured on one part of the site. For example passing three parameters to a global the first parameter was dropped. On other pages of the same site this issue didn't happen.

Anyway, after spending some time searching for an error, I found out that deleting all pre-compiled templates for that set solved the problem.

Can anyone confirm this issue?

If so, GT might want to add a bold red line stating 'delete your compiled templates after upgrading' to the updater. Saves a lot of time...
