Thank you for response Zrevnur. I did not had a lot of hope that anyone would actually notice this thread. I thought this specific issue what was described in this old thread: https://forums.elementalgame.com/450960/page/1/#3440852 But it sounds like there is another larger bug going on.
I recently reinstalled Fallen Enchantress legendary heros and noticed a bug where wilding shaman's summon wilding spell consistently does nothing. Doing a search at this message board I found out that it was a known issue and some people even had mods that fixed it. But those are very old locked posts and links to those mods no longer works :(. Would anyone still have one of the mods that fix this issue available and be willing to share.
