This mod aims to repair the Stamina Costs Rebalanced mod by Captain Crunch - (https://www.nexusmods.com/witcher3/mods/1335), as the mod breaks the yrden sign. I have recooked a mod version to fix this bug. The fix has worked on my playthrough and should work on yours.

I highly recommend using this in conjunction with mod ESGO - (https://www.nexusmods.com/witcher3/mods/1185) as I find the ESGO balancing works really well with the half cost of signs. Also, you can tweak combat to your liking with ESGO.
To install, simply unpack the file in your witcher 3 mod folder and merge any conflicts with script merger.
