My work-around for frequently-used DIY routes and sessions has been a simple, pragmatic change in locomotive and vehicle orientation for longer consists being produced by portals, since it is not only locos involved in ex-portal coupler-breakage incidents.
I don't use portals much in any of my routes, but one or two sessions benefit from the additional traffic generation they afford.
Bottom-line however, is that SP3 is such a massive improvement in most other respects over all previous builds that these minor niggles (which will be fixed soon no doubt in a asset update rather than a Hot-fix release) should not be used as an excuse for not updating.
