The mesh for the Trama plant is currently bugged, as the empty space surrounding the Trama plant is considered solid and is therefore impassable. As a result, the plant has become a major obstacle.
This issue is most prominent at Assalkushalit Shrine on the north face of Red Mountain. Here, a Trama plant is leaning over the end of the wooden rope bridge leading to the shrine, making the bridge impassable!
The solution to this issue is to install the mesh fix "Resource Pack" mod Qwerty created for inclusion into v056 ( http://morroblivion.com/forums/morroblivion/morroblivion-development/2981#comment-21284 ). However, it appears that this mod wasn't integrated into v056 after all, as the Trama mesh issue still exists in v056. Once the mesh fix "resource pack" was installed on my computer, the space around the plant was no longer considered solid and i was able to pass over the bridge.
Hopefully this mod can be integrated into v057, when it is released!
Edited to make it clear that installation of Qwerty's "Resource Pack" is necessary!
