Sorry for not responding earlier, my college just started back up and that has been taking up my time. I am unable to replicate this with Bob's tech and Science Cost Tweaker installed: My burner lab is in the right place, and it is the Bob's burner lab as opposed to another lab. Could you post a picture of you hovering over the lab recipe with the yellow text showing up like this? The information in there is actually very helpful.
Since it is not my mod that is not putting the burner lab in the right place, I think you should ask Science Cost Tweaker's author to fix this for their Bob's mods tweaks.
as I suspected, AAII's lab is in SCT section. I dont have AAII because along with SCT makes modules imposible to research, as I told you in other thread, doesn't this happen to you?
When I originally said I couldn't reproduce it, I had AAII on (that was the picture). I got exactly what you got when I turned AAII off. I am going to take a look at the module issue you mentioned.
Took a look at the "modules being unresearchable" issue, and I have made a bug report here. I can't imagine it won't get fixed given how I've provided the exact mechanism and a solution, hopefully mexmer will see it soon.
