1. Fixed optimization issues in most maps. (Overflowed CClientRenderablesList group 8)

2. Fixed player not being able to progress in the Combine Facility.

3. Soundtrack changes have been made in this update.

The first map of the mod now uses "The Nectarium" soundtrack twice, at the beginning of the map and near the end.

The first usage of the soundtrack happens during the ascension on an old elevator. Overlooking the birds and the horizon during a slow-paced moment, it creates a compelling atmosphere in an otherwise empty and quiet scene. If the player chooses to rush during that set piece, the soundtrack ends near the moment of unexpected tension.

The second usage of the soundtrack happens if the player defeats the final gunship. The "battle" soundtrack that originally kept playing uninterrupted during the confrontation of the gunship, even when the player defeated a gunship, now ends properly. Shortly after the "battle" soundtrack, delayed "Nectarium" plays yet again, signaling that the player is now safe for the rest of the map, creating a powerful, meditative moment. If the player decides to run and drive away from the gunship, the "combat" soundtrack keeps playing until it's over.
