SourceScramble does not recognize the [platform]64 (platform-specific) keyword and fails.

SourceScramble does not support the [platform]64 tags and causes all other valid platform-specific patches to fail. (see mempatches.cpp)

Here's the config in question. https://github.com/zxz41/disable-truce-hotpatch/blob/d1b57a75b44061a592f4e8dcccbbdc61e958f1a8/gamedata/tf2.valvemaptrucepatch.txt

Will close when fixed, once 64-bit support lands for Source Scramble (soon™).

There are now prerelease builds of the extension that introduce 64-bit support.

I briefly tested it against your patches and the manager plugin reports that they were successfully applied, but if you're able to report back with your own testing, it'd be appreciated.
