Unable to add LongPtr as key or value (twinbasic version: 980), 64bit

[AlaskanDruid]

When trying to add a LongPtr variable as a key (or) value, the IDE spits out the following error:

000E 14:44:18.351 NATIVE EXCEPTION: ACCESS_VIOLATION /Mazikeen.twin; Mazikeen.Class_Terminate LINE 000064 [$00000001806508F5:twinBASIC_win64.dll+006508F5]

Ah please disregard. This is inconsistent. Works fine in some projects, but throws the above errors in other projects (even fresh ones).
