水池中水生小动物存在判定问题

English：

1. Aquatic creature detection extends beyond the actual pool boundaries

The game's detection of whether a pool contains aquatic creatures appears to incorrectly extend two tiles horizontally from a water tile. Based on my testing, this behavior depends on the order in which rooms and creatures are created or updated. I have not tested whether the same issue occurs vertically, but it may behave similarly.

As shown in Figure 1, the topmost water tile on the left incorrectly counts the Fish Eggs located two tiles to its left and right as being inside the pool. However, according to the room overlay, the pool itself contains only 12 water tiles, and the tiles containing those Fish Eggs are filled with gas rather than liquid.

In Figure 2, the behavior is normal: within the same 12-tile pool, only the actual submerged Puft Fish (or other aquatic creature) is counted as being in the water.

2. The bug can be reproduced consistently based on the order in which aquatic creatures enter the room

This bug can be reproduced reliably depending on the order in which Fish Eggs enter the room or the pool.

As shown in Figure 3, when two Gulp Fish Eggs are transported into the room via the conveyor rail before entering the pool, the pool correctly reports that it contains no aquatic creatures.

Then, as shown in Figure 4, when a third Fish Egg is delivered directly into the pool through the conveyor at the lower left, the pool correctly reports one aquatic creature.

However, if a Fish Egg enters the pool before the others, the bug occurs.

As shown in Figure 5, when the first Fish Egg enters the water, the pool correctly reports one aquatic creature.

Then, as shown in Figure 6, another Fish Egg that enters the room but remains outside the water is nevertheless incorrectly counted as an aquatic creature inside the pool.

This behavior appears to depend entirely on the order in which the Fish Eggs enter the room and the pool, making the issue consistently reproducible.

1.水池中是否有小动物的判定（取决于出现在房间的先后顺序）会辐射至一格水的左右两格（是否有上下本人没测试，但应该会有）， 如图1：左图中最上格的水将左右两格的鱼卵计算在内，然而在房间显示中水池只有12格（鱼卵在的位置均有气体）。 图2则是正常版本，12格的水中只有鼓气鱼被算入水中。 2.该bug的触发取决于水生动物出现在房间的先后顺序可稳定触发。 如图3：当前两个大嘴鱼卵从运输轨道先进入这个房间时水池中显示没有水生动物，而向水池中通过左下角的轨道向水池中加入第3颗鱼卵时， 如图4：水中显示只有1个水生动物。 但先让鱼卵进入水池中则会触发此bug 如图5鱼卵先进入水中显示水中只有一只水生动物 如图6后进入房间但未进入水中的鱼卵被计入水池水生动物中
