I just ran into this problem yesterday. I updated to the latest daily build (Version 2014.2155 (2014.1.25)) so I could get the GameAnalytics stuff. Prior to yesterday, I don’t know what version I was running, but I hadn’t updated for 4-6 months maybe. But after updating, I noticed one of my scenes just blew up, and had stuff all over the place and wrong. Took me a day to track down one of the issues is the text.size bug.
I used this prior just fine. I used it for the purpose of the user selecting one of 3 things to say to NPC, and the one they selected would do a transformation on the size to enlarge it as well as center it. It worked perfect, and now not only is the .size broken, but transforming the x/y coordinates with an reference point set is broken too. Now I have to recode a module I had working perfect for almost a year to fix these bugs that popped in.
