Seems like the only way i can be sure the modifications i make will not be deleted is after a compilation. Can anyone help me with this issue please?

Basically im programming inserting or editing blocks and suddenly they disappear or return to it previous state.

The only think that will cause this is if you are working in a auto generated CFC (used for driver blocks) or F blocks (safety matrix blocked, generated whenever you compile your safety marix) or if you update the process tag type. If this is not the case then can you please confirm which runtime group it is adding the blocks (the runtime group can be found out by clicking on the green box on the block) Hope this was helpful. If this does not help then please send some screen shots. regards, Minhaj

This can happen after i did a lot of changes so is kind of frustrating. im receiving one message error continuosly that perhaps has something to do with the problem, i add a screenshot. any idea?

It is a common practise but I though it is worth mentioning in case you haven'tdone it? regards, Minhajie

Behaviour of the problem is weird, sometimes i can work for days withput problem, and somedays its frustrating, it continuosly undo every change i made. I've noticed it happens more when i modify block parameters or use copy/paste/cut to copy blocks or DB addressess. I've thought about reinstall the software but it takes lot of time and im not quite sure this is the problem.

PS: You can do that by right-click on your blocks folder and the select the tab on the window which will appear. it might be the case that you're following an addressing priority different than the one set for your project. And this is ture only for the connections made to CFC blocks and not the block itself. Kind regards, Ghassan
