I got the error when placing a display panel

The mod Display panel can display circuit amount as text (1.0.7) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event display-panel-can-display-circuit-amount-as-text::on_built_entity (ID 6)
...y-panel-can-display-circuit-amount-as-text__/control.lua:22: assertion failed!

is anything overlapping where you're placing it?

Well it was next to a diagonal rail segment.

It is where the display panel is (with the mod disabled)

fixed in 1.0.8

Thanks!
