It has come to our attention that the Bismarck "teleports" in Operation Rheinubung during the Swordfish stage. We have identified the bug and this is the patch to address it.
To install this patch simply extract the contents into the Bismarck Mission Pack folder and replace any files when prompted.
Please note that this patch only applies if the Bismarck Mission Pack installer does not show "Welcome to the Bismarck Mission Pack (with Patch A) Setup Wizard" on the first screen.
If the installer shows the above text then you already have the patched version and this patch is not necessary. The patched installer file is also named Bismarck_Mission_Pack.1.exe
