pythia generates 99 events

Asked by Harikrishnan Ramani

an hour back, all of a sudden pythia+pgs stopped generating the full events producing only 99 events.
I then redownloaded madgraph and installed it and so did my advisor. we all installeded madgraph out of the box and installed pythia-pgs inside the madgraph module.
We find that pythia,pgs generates only 99 events.
The pythia.hep is as fat as before but the pythia.lhe and the pgs.lhco both contain only 99 events!

On further investigation we found that the update on April 1st pythiapgs2.2.1 carried the bug and reverting back to pythiapgs2.2.0 solved the problem.

The computers used were mac. Just wanted to let you guys know!
