模组 厂房2 (2.5.1) 引发了无法恢复的错误。
请向模组作者报告此错误。

Error while running event Factorissimo2::on_research_finished (ID 18)
LuaForce API call when LuaForce was invalid.
stack traceback:
[C]: in function 'create_entity'
Factorissimo2/control.lua:312: in function 'build_lights_upgrade'
Factorissimo2/control.lua:1386: in function <Factorissimo2/control.lua:1375>

实际上，我不知道这是不是我的操作造成的，希望你可以帮我解惑

It seems like your factory building was first built by a player using a force that no longer exists.

If you recreate the force in the editor, the invalid LuaForce in your error message will be valid again (tested in 1.1.21) and you will be able to use your factory building again.

To recreate the force, type /editor, click on the flag tool, and enter the exact name of the force in the text box below.

If you don't know or remember the name of the force you used to place the factory building initially, please upload a save and I will help you find out.

太感谢了，我按照你的方法处理好了我的错误，mod我非常喜欢，让我的电脑不至于宕机
