After I shift-rightclicked the Terrestrial Agglomeration Plate with the Lexica Botania (which was the first thing I ever clicked with it, btw.) the font size changed to something slightly too large: https://i.imgur.com/Ag4DnPM.png
This does not seem to be reversable.

I sadly don't have a log from when it happend, but here is the latest, maybe it has some usefull information: https://mega.co.nz/#!eZZn0KSD!XAIOlNH9slATEx9X2Cv7NrBJwfcX5zkUbSmOrUP9PdY

What in the actual fuck? O.o

Lolwut

Yeah, I can't reproduce this.

Edit for less sass.

Took a poke at it, tossing Botania and Reika's DragonAPI v4c into a minecraft setup should let you reproduce it, although I'm not sure if that'll help resolution at all.

And here I was hoping to find a solution to this somewhere. Time to go forge version meddling.

It has something to do with the custom font hooks in Dragon API added in v4.

Gg @ReikaKalseki ...

In v4, I added code that basically makes the FontRenderer delegate strings beginning with certain substrings to custom font rendering objects. This was done because NEI craps all over the font rendering code and most of the ability to use a custom font renderer properly is broken with it installed.

How exactly does the Botania font rendering work? Do I need to entirely rewrite the system, or is this the result of a simple oversight somewhere?

I don't have any, all I do is use setUnicodeFlag.

Hm....the good news is that this may then be a simple fix.

OK, I just added this for inclusion in v5.

this.setUnicodeFlag(fr.getUnicodeFlag());

Hopefully it fixes it; v5 will be out later this week, or, if you want, you can have a copy early to test.

v5 successfully fixes this issue.
