There's an update in bleeding_edge, if anyone fancies trying it. I think I finally found all of the potential issues with joints attaching to null. I've had *ridiculous*-sized motherships now and absolutely no physics tornados. Prove me wrong! ;) V1.11 -Joint disconnection is now smarter and 2-way, avoiding a potential 1-tick issue with joint forces. -Fixed issue with dangling Twin Distance Joints. -CPU Optimisation to rotating objects -Low Detail now uses lower-quality normal maps. -Fixed an issue causing a huge GPU performance overhead with non-instancing sprite rendering. -Added some missing pad vibrations -Fixed issue with a single distance joint filling up all the slots -Removed unneeded physics joints for CPU performance I haven't got time to test it properly before travelling for Christmas, so it'll sit there for a bit - feedback welcome!
