After updating t4 plugin and template on my site i noticed that in different pages modules positions dont work properly. They just disappeared. Somewhere they works fine.
Then i try to clean T4_cache. And refreshed page - modules works fine. But in other pages modules still not shown. Then i tried to clean every page that i open. But problem with module loading starts on over and over. Unstable.
When i disabled T4 cache(Development mode ON) - everything works fine. BUG with cache??
Problem started when i updated from 1.1.0 version.
