Can somebody help me with mapping for quoth? The biobox(just a themed explosive crate) entities do not appear in the level for some reason when I use the builtin quoth .fgd(trenchbroom user). Other entities from quoth like plasma gun and modified grunts appear in the game fine.
I tried to fix it by manually loading the .fgd from latest quoth and it does work, but entity previews are gone when I do so(pic related) which makes placing items well difficult
I could just use the builtin for mapping and manually load the new one for testing but its kinda tedious, anyone knows how to fix these previews?
Thanks!
