Issue when increasing maxlevel from 11 to 12

[Nivesh Mishra]

Dear Basilisk Users,

I am currently running a simulation where everything works fine up to maxlevel = 11. However, when I increase the resolution to maxlevel = 12, the simulation throws an error and terminates unexpectedly.

Abort(644354) on node 0 (rank 0 in comm 0): Fatal error in PMPI_Recv: Invalid count, error stack:
PMPI_Recv(204): MPI_Recv(buf=0x2ba1e4293010, count=-2089621016, MPI_BYTE, src=1, tag=256, MPI_COMM_WORLD, status=0x1) failed
PMPI_Recv(107): Negative count, value is -2089621016
[cli_0]: readline failed
Abort(604617730) on node 1 (rank 1 in comm 0): Fatal error in PMPI_Isend: Invalid count, error stack:
PMPI_Isend(152): MPI_Isend(buf=0x2b6e64422010, count=-2089621016, MPI_BYTE, dest=0, tag=256, MPI_COMM_WORLD, request=0x7ffeb89a02e4) failed
PMPI_Isend(97).: Negative count, value is -2089621016

Has anyone encountered a similar issue? Could you please guide me on how I might resolve this problem or point me toward possible causes?

Thank you in advance for your help and suggestions.
