Why are the official .VMF's so leaky and broken?

    A friend of mine recently decided to remake official maps using the official .VMF's that were published by Valve on June 15, 2009. However, the two maps he touched are already broken when trying to compile them, either giving leaks or fatal errors related to areaportals. I helped him fixing a CONTENTS_SOLID problem on the first map by deleting a SKIP brush (since no other workaround could help). The second one, however, is giving us both just troubles because of entities outside the maps, many areaportal errors and constant game crashes. It's just that; we open these maps in Hammer and just compile them without performing any changes, and all it does is report all these problems. Did Valve actually break them intentionally or are the updates to Hammer responsible for it? I just keep seeing that VBSP, VVIS and VRAD usually have different dates (latest: June 14, 2017).

    Here's the compile log of, let's say, sfk_ctf_2fort.vmf, and it's just the VBSP (no VIS nor RAD):

    Most of the maps are decompiles and that process isn't 100% error free

    Your comment has nothing to do with the post.

    Source SDK comes with the original official VMFs of the base maps that were launched with TF2, so they're def not decompiled copies.

    The engine has changed so much over the years that compiling maps that are this old is nearly impossible. For example, you would need to turn half of goldrush and hydro into models or you will consistently hit the brush, brush sides or t-junct limits.

    It might also happen that hammer has trouble loading a brush. When that happens, hammer will say that one or more brushes couldn't load and it asks you if you want to save the map with the broken brush removed. Redownload a fresh copy from the SDK and see if it does that. If so, you will have to find the brush yourself somehow as no tools exist for that.

    I expected the TF2/Hammer updates could've brought problems when it comes to compiling a 2009 .VMF with all that content in it. And no, neither of the 2 maps we tried to edit had invalid solids; Hammer loaded them up properly, but to fix a problem in the first map I had to remove a Skip/Hint brush, which is absurd yet useful to fix the issue.
