After the commit 60ea783, we've had MPRESS unpacker bugged. Specifically the part which copied sections from packed PE into unpacked PE, which were not modified by packing process at all. This resulted in files unpacked by our
retdec-unpacker
to miss things like exports, resources and other things which are usually placed in their own sections (apart from imports which were properly reconstructed and unpacked code).
