Known issues:
* Brimstone lasers fired by Door will hit yourself, this is due to an vanilla issue which makes brimstones fired by friendly enemies hit yourself.
* Something that destroys rocks, and make Mama Mega explosions will cause errors, rep+ devs changed the function to destroy obstacles, but they didn't make compatibilities.
* The render position of active items is incorrect.
* Yamawaro's Crate will crash the game when taking out an item from the crate due to a Mod API change.
* Enemies summoned by Isaac or his familiars cannot be damaged by his tears, like UFO from saucer remote. This is a vanilla issue where spiders thrown by Dark Bum can also not be damaged.


目前已知BUG：
* 門发射的友方硫磺火会打到自己，这个是原版问题，原版友方硫磺火苍蝇爆了也会打到自己。
* 某些摧毁石头的东西会报错，官方调整了这个函数，然而他们没做兼容。
* 主动道具的显示位置歪了。
* 由于MODapi修改，山童的木箱在取出道具时会导致游戏崩溃。
* 被角色或者跟班召唤的怪物无法被角色的泪弹伤害，如飞碟遥控器的UFO。这是一个原版就有的BUG，黑暗乞丐扔出的蜘蛛也是这样。
