Your Expectation

There is an issue present that was fixed in upstream here: SleepyTrousers/EnderIO-1.5-1.12#5125

See the related issue here: SleepyTrousers/EnderIO-1.5-1.12#4773

The Travel upgrade for EnderIO tools has an interaction with some graphics optimization mods that mess with frustum culling, causing the vector cast for finding a travel anchor to travel to to not check whether the anchor is along the vector in front or behind the player.

Ideally the player can only teleport to the travel anchor they are looking at. You can trivially reproduce this issue by placing a travel anchor behind the player and trying to shift right click. This will teleport the player backwards.

The Reality

With this bug, having a travel anchor behind the player counts as "selected" and will teleport you backwards.

Your Proposal

The implementation changes in the linked PR from upstream should be backported.
