🐛 Fixed 'L' not locking slidenodes.

PROBLEM: typo (a copypaste derp) in GameContext.cpp

ADDITIONAL FIX: an assert() when loading Penguinville-TrolleyLine terrain. The blendmap info was incomplete (understandable since the game is meshed-only) and the game ended up reading bad memory. Fixed by adding a check for valid data which reports "[RoR|Terrain] Page {}-{} has no blend layers defined, blendmap will not be set up." to RoR.log.
