Having issues with initializing case in 33.4 version.

My case built and initialized with no errors on work PC having version 33.9 shows multiple initialization errors on another PC having 33.4 version. Same case perfectly initializes on version 33.9. Some things that i dug up while trying to solve the issue. e.g if Vmax of some governor is correctly tuned in 33.9 version, that value shows initialization out limit error in 33.4 version. if Vmax=0.80 in 33.9 version i have to make it 0.83 or 0.84 in version 33.4 for this error to be removed. So, i have to do this tuning exercise again and again. Extremely annoying. Anyone else facing same issue?

Check with PSSE release notes. If there is no change in governor model then try checking your simulation/parameter setting and make sure those are same in both the versions.

And this happens only for governor models. Would be glad if someone could help. i have to make TRATE of GGOV1 from 300 to 301 and then suspect error is removed. but case initializes with no error TRATE=300 in 33.9 version

Can you show load flow and dynamic data for a generator and the error messages?

it is clear that Vmax should be 0.80 or greater. i put 0.81 but still getting initialized out of limit error. i have to put 0.83 or greater for this error to be removed. this only happens in 33.4 version. in 33.9 it initializes without any error

Similar problems for other machines too.
