Have you applied all the permanent fixes in this sticky? yes

Have you deleted map.rwm? Yes

Have you tried the temporary fixes in the sticky mentioned earlier? I've Install the hotfix 0.81a3
I understand it like you have installed the hotfix over 0.81a v2. This is not a good idea, as the hotfix was meant for 0.81, and was upgrading it to 0.81a. 0.81a v2 contains everything good in the hotfix and more, which you've currently discarded by installing the hotfix on top. There is understandably confusion concerning the version numbers. You should install 0.81a v2 again to undo this damage. There is no need to install the permanent fixes as they are already part of 0.81a v2.

The hotfix is not what is called temporary fixes. Please read the sticky with fixes again, and follow the instructions given there for how to apply the (three) temporary ones. There is no need to download them as you already have them with v2.
