@dara1400 I don’t have my computer in front of me, so can’t check exactly what worked for me previously, and like @yv001 I have yet to try a custom LM with 0.5.0.
If you could post the commands you’ve used I can try to have a look tomorrow evening (or maybe the weekend, depending on my timing) .
My general principle here is I’m happy to help (within reason!) if you can make the case you’ve put in some efforts with exploration of the forum, source code & done that kind of leg work already.
