 - If the loop requests a running TBR to be cancelled the Combo will set a TBR of 90% or 110%
   for 15 minutes instead. This is because cancelling a TBR causes an alert on the pump which
   causes a lot of vibrations.
+- Due to the bug (which causes the pump to become unreachable when reading history regularly),
+  a delivered bolus will NOT be added to treatments when the connection was lost during bolusing
+  or when a pump error occurs (e.g. occlusion). This will raise a message (and play an annoying
+  sound) and the user will have a create a bolus record via Careportal/NS manually. Currently
+  this requires an available NS installation and being online (for a short time). Hopefully
+  both of these issues can be resolved in future versions.
