New version B20-just wiped all my add on indicators

[raycam]

I have a number of indicators that are no longer working and need recompiling. I have an error messageCS1061'NinjaTrader.Gui CHartHorizontalLine' does not contain a definition for 'AttachedTo'
Normally the recompiling goes off without a hitch. not today.
Could someone help me please?
Cs1061 has nothing in the help menu

raycam, this was a code breaking change as described in the release notes.

OK.
If I had any clue at all what that meant I might have not updated so quickly.
Is there a way of sorting that issue from my end?
I have at least 5 indicators that are no longer showing up?

Raycam, unfortunately not since this was an unsupported method.
