Ok, I think I have found a new issue:

The builder still allows loading and working with external indicators (My indicators), but when loading the experts in MT4 and trying to run them, the smiley face in the right corner, everything seems cool but...nothing happens; the signals occur on the chart but the expert just ignore the signals completely. I have worked with the same indicators for a couple of months now and never had an issue until now. The funny thing is that this problem only happens to me with external indicators, because if the expert was created with internal indicators then it works fine. However, this is a big deal for me since all my experts work with external indicators.

Could someone else please confirm if this is a general problem or maybe it's just me?

Hi,
I'm afraid the problem persists. I was about to finish a project and suddenly the size of the blocks changed and returned to default settings T.T

Thanks in advance for following up.

Update:
I also noticed that all the information on the "Project Options" section has been deleted as well.
