Jack Croft played on the wing for 40 minutes in the second half and scored twice.

The Siddal try still looks like a lost ball going forward on the highlights vid. Thought that at the time. Still can't see the reason for extra penalty after he missed the conversion.

I thought that tbf. I was thinking maybe he dabbed it through but was defo lost forward, much to the disbelief of Lino and Jerry.

What was the foul play that gave them the follow up penalty?
It must have been something during or just after the actual act of scoring.

Yeah, see my subsequent post

Club on X said it was a penalty try

It wasn't a PT though as first conversion was from in line, with the "try".

PT is given in front of the posts.

It was given as a foul in the act of scoring, hence an 8-point try (attempt at 8 points) = 1st kick in line, 2nd kick in front of posts.

Penalty try, foul in the act of scoring...I say just let it go, they deserved a try. We move on, and we'll have bigger issues than that to fret about this season, I'm sure of that.

No issue just clarify.
It wasn't a penalty try but it does look like Jowitt was penalised for a head shot during the act of scoring hence the extra kick in front of the sticks.

Indeed.
A penalty try is when no try was scored because the defender did something against the rules to stop it. So try is awarded.

An 8 point try is when an infringement happens in the act of scoring so the try is awarded, kick takes place, then a penalty is awarded.
