I don't have a steam version, but a DVD and i have the identical problem in the same place. Game is patched, it's 1.2 version. The game is seriously bugged (btw like Anniversary and Underworld), climbing always was glitched as hell, but that place in Croft Mannor is a peak of annoyance, because it makes impossible to get a damned reward. My graphic card is NVIDIA GeForce GTX 1060 6 GB and CPU is Intel Core i7-6700K 4GHz, if that makes any difference. EDIT: I tried to record the bug with video recording program and it... didn't occur! Furthermore... it doesn't occur every time i'm recording the game! However stupid it sounds. But i think i see correlation now. When recording was turned off it showed that the game had over 400 FPS. When i turned recording on it dropped to 60 FPS (video recorder slowed the game down to make a video). It looks like too high FPS rate caused by faster hardware breaks the game. Btw recording program is Action Mirillis, but i think the bug may be fixed by reducing FPS rate with different programs too.
