When l chose red dragon for my draconic bloodline sorcerer, the elemental affinity says lightning not fire. Also bronze dragons say acid,which sounds wrong. And brass says lightning. Lots of dragons give the wrong type of resistance.

This is happening to one of my wife's characters too.  Black dragon bloodline but lightning on the affinity and it says acid on the sheet.

Are you going straight to higher levels?

The issue in diplaying the wrong affinity in the builder is a caching issue where you select the ancestor, level up to 6 or more, then change your mind and choose a different ancestor: the affinity bit remains unchanged. This is because it caches it. If you go to the sheet or just refresh the page, it will be resolved. If you are levelling individually and never change the ancestor type, this issue doesn't occur.

This is a limitation of how browsers and memory work, not a bug. It is possible to use different code and not use caching but that eats at the server bandwidth. Unless you want a loading popup/screen every time to select something?

The affinity that gets shown on the sheet is correct - I have tested all options, all give the correct affinity.

Not going straight to higher level, nothing but black has ever been selected.   Brought up the character just now, was showing correctly.  Looked at something else, specifically something in Against the Giants, went to the character again, through the menus, and now it's showing fire as the affinity.  It's obviously a bug.   When you print the sheet itself out it does seem to be correct.   You'll have to try testing again, oh...sorry didn't see "moderator" next to your name.  I'll post where I want thanks.

I'm having this same problem. I'm gold draconic bloodline, should be fire. It's bouncing between acid, lightning, cold, and fire.

I have the same issue. I have 2 characters with Silver draconic bloodline.

One shows Lightning Elemental Affinity:

Thank you, it appears to be fixed now.
