Hi, its your release notes reader here. Gota question about the latest overwatch version which can be found in update history testing. Version 123e and 123d seem to have the same release notes as far as I can tell.

• • Potential fix for script error in FixComboRabbitHoleMetaAds:AddContainedRabbitHolesToLot when a save has bad data.
  • Potential fix for script error in RepairImaginaryFriends:OnDelayedWorldLoadFinished when a save has bad data.
  • Fix for script error in GhostHunter:ApplyCareerSpecificModifiersToXp when an inactive ghost hunter ages up.
• Version 123a
  • Removed the base camp EP11 translation modifications from this mod and moving them to an upcoming version of traveler with a much simpler approach.
  • Should no longer eat cars on ani's car displays.
  Version 123b
  • Forgot to remove the code when I removed the base camp string resulting in a blank entry in the lot type drop down.
  Version 123c
  • A more aggressive approach at killing runaway trick or treat alarms.
  • Fix for an EA fail with broken NPC parties that would render the save unplayable.

Is thee a difference between these 2 versions? Sorry to be annoying

Yes there's a difference. Always get the latest. The older versions remain in case there's an issue with the newer version.
