[NTG-context] Gathered equations with t-amsl and t-nath

Hello Giuseppe, you've done a great work with amsl an nath modules! Seems that there is a little bug when you try to gather more than two formulas: \placeformula \startgather f(x) = x \\ g(x) = x^2 \\ h(x) = x^3 \stopgather When doing so, I end up with the last two equations on the same line, with the same equation number. Thanks! David
