Zinglon

Title describes all.

So I entered the secret room in one direction. And find another secret entrance that leads to same secret room in another direction. When I enter the latter entrance to secret room, I teleported to nothingness and cannot interact with anything. Fig. 1 : Showing a secret room with double entrance. I entered there first from an entrance room of a ruin, then found another door in other room of the ruin, and tried to enter there. Fig. 2 : When I entered the secret room via the latter entrance, I cannot interact with anything. Fig. 3 : As like the Black Room bug, I teleported to nothingness (you can see my Wolfgang's indicating button in the north of blackness, while the map of ruin are located southeast).

While frogs are swimming inside the water, their sprites are not shown.

Check these screenshots. You can see a watery ring around transparent snakeskins on the ocean.

Check.

Why?

HAM->SW->HAM->SW results in starting at Seaworthy.

Ro Bin cannot follow the ship, just stuck somewhere of the ocean.

BFB have been trying to destroy the pig farm, but since it's indestructible hence it stuck in there forevermore.

So I packed several items for SW in hamlet then depart with Skyworthy, I found that Ro Bin's inventory is lost after arrival.
