From what I understand, when using the Factorio+, AAI and Refining mods, there are two kinds of recipes for sand and glass, one of which cannot be created, which blocks some items. Since there is compatibility between AAI and Refining, I assume the problem is with the Factorio+ mod. Is it possible to fix this?

Hi engineer.
I don't personally know Factorio+ mods. (Despite the title feels a bit weird to me if you watch my modpage, but lol just it makes me smile.)
Said this, yeah when AAI is found together with Ev Refining my mods work around Earendel's intermediate, as it is definitively more popular and more used than the one added by my mod - and having two different types of sand doesn't make much sense.

You should ask to the developer of the Factorio+ modpack if he can do something about that.
Currently I'm "exiting" from an exam session, and I've enough bug reports to fill multiple A4 pages... so major non-already supported compatibilities are not a thing for now - at least from my side.

Is the thing still an issue?

Hello,
I will write to the creators of the Factorio+ mod about the issue, in case they can add compatibility with your mod. I am currently on a business trip, so this incompatibility does not cause me any problems at the moment. Thanks for your mod. If the creators of Factorio+ are unable to solve the compatibility issue for some reason, would you mind if I make a follow-up post about this issue in about five months? Thanks again for your work.
