We have recently released update 2.20.1 which introduces several fixes, one in particular with the License Server module where a missing error detection would not trigger the “grace period” under specific circumstances.
We highly recommend that you download and apply the latest patch to address the problem described. The patch is also available for older versions, starting from SFS2X 2.12.0.
