Well ... it is generally asserted that 1.12 is a success, in terms of an update that didn't break a whole load of new stuff. Fair enough. In my terms, however, it isn't a success, because I am still being bugged by the same old building bugs that have been driving me crazy for months and months. Plus I have a new lag problem which is affecting other people too. It's making building a pain, difficult, not enjoyable at all..
The "link failed, pieces too far apart" bug is still alive and well. This refuses to link an object even if the object is well within the maximum size available. In some cases I have had this message with hair and small objects, or with an object in the middle of an already linked object.
The "can't stretch inidividual prim of linked object even when you check edit linked parts" bug is alive and well. This means that if you try to stretch an individual prim in a linked object, it stretches but immediately springs back to its original size, until you unlink it.
The bug ... well I presume it is a bug ... which means that if you select a couple of prims from a linked object and delink them, the whole object, both unlinked and linked parts become selected, is still with us. This has meant recently that I inadvertently retextured a whole build because I hadn't realised the whole object was selected.
The bug which means that you can select three prims together, try to rotate them as one object and find that they are all rotating separately, but at the same time, is still around. Annoyingly, if you try to revert back by reversing the procedure, they will invariably then act the way that they should, as one object.
In addition, I am getting a delay between clicking on a texture window and seeing the texture picker open. It's only a couple of seconds, but when you are trying to retexture a complex object it makes everything so sloooow.
Oh, and I crash when I try to sort inventory or delete anything from inventory.
Fenrir reports on the forums problems with building in an empty sim with no connection problems, and I have the same problem. I had a discussion with one other avatar in an empty sim and was getting a 10-15 second delay on chat appearing.
I don't know what's up, but it is making trying to build for the project I am building for very frustrating indeed.
