License counter issue

A new Lua version causes a failure of the license counter checkup leading to a ”Invalid license specification” error during sbatch submission.
As a dirty workaround we allow/suggest this week to remove the flag "-L ansys" till the problem is fixed on our side.
The downside of removing the flag is a job start while all our purchased licenses are potentially occupied by other users - leading to a cancelled job.
Because a moderate license load is expected this week, the workaround is worth the risk. We remove this message here ASAP "-L ansys" can be used again.
