Parts of Charlie can be shoot and walked through XCE 0.33 HF2

As can be seen in attached screenshots, after installing XCE 0.33 HF2 - it is possible to shoot through and also go through the Charlie.

I checked - it's enough to bring back 0.33 HF1 and the problem dissapears even when restoring the same save (so I guess some spectres got changed?).

Only the "pilot" part of Charlie is affected, the soldier part is still solid.

I did some experiments - I do not know how the hidden_block_spectre.xml file in xce\tiles\dropships\chinook is supposed to work, but I think it doesn't. I modified the Chinook cabin spectres so the default cabin again has

visibilityScore="0.000" bulletScore="0.000"

That solved the problem for now, I hope I did not break anything important by such tinkering. ;-)
