same here

likewise here

same here, another mod I used had a similar sort of error. Someone figured out how to fix it I don't know enough about the changes that prompted this to "port" that change unfortunately... probably...

ok figured out how to work around this

change line 157 FROM:

 flowPI.add({ type = "frame", name = "framePI", caption = entity.localised_name or {"entity-name."..entity.name}, style = "dialog_frame" })

to read:

flowPI.add({ type = "frame", name = "framePI", caption = entity.localised_name or {"entity-name."..entity.name} })

basically remove the style argument and it works well enough

@coffee_fiend, many thanks for the solution!

Fixed, I'm very fast
